Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Indemnifications In the normal course of business, we enter into agreements that contain a variety of representations and warranties and provide for general indemnification. Exposure under these agreements is unknown because claims may be made against us in the future and we may record charges in the future as a result of these indemnification obligations. As of October 2, 2021, we did not have any material indemnification claims that were probable or reasonably possible. Commitments We maintain commitments to purchase inventory from our suppliers as well as fixed assets, services and other assets in the ordinary course of business. As of October 2, 2021, we had total estimated significant purchase commitments for inventory of approximately $63.8 million and significant purchase obligations for fixed assets and services of $50.6 million. Legal Proceedings We are subject to legal claims and litigation arising in the ordinary course of business, such as contract-related, product sales and servicing, real estate, product liability, regulatory matters, employment or intellectual property claims. Although we do not expect that such claims and litigation will ultimately have a material adverse effect on our consolidated financial position, results of operations or cash flows, an adverse result in one or more matters could negatively affect our results in the period in which they occur, or in future periods. The United States and many foreign governments impose tariffs and duties on the import and export of certain products we sell and purchase. From time to time our customs compliance, product classifications, duty calculations, and payments are reviewed or audited by government agencies. Any adverse result in such a review or audit could negatively affect our results in the period in which they occur, or in future periods. German authorities are currently investigating an export compliance matter involving one of our German subsidiaries involving four former employees (whose employment was terminated following our discovery of this matter). While under German law the subsidiary can be held liable for certain infringements by its employees of German export control laws we believe that this matter involves less than approximately 1.5 million Euros in transactions in the period currently under investigation and do not believe that the final resolution of this matter will be material to our consolidated financial position, results of operations or cash flows. However, the German government investigation is ongoing and it is possible that substantial payments, fines, penalties or damages could result. Even though we do not currently expect this matter to be material to our consolidated financial position, results of operations or cash flows, circumstances could change as the investigation progresses. As previously disclosed in the Company's Quarterly Report on Form 10-Q for the quarterly period ended April 3, 2021, filed with the SEC on May 12, 2021, on April 28, 2021, a purported stockholder of the Company filed a complaint in the United States District Court for the Southern District of New York against Coherent and its board of directors alleging violations of the federal securities laws for misleading and incomplete disclosures in the Registration Statement on Form S-4 (the "S-4") filed in connection with the Merger (Stein v. Coherent, Inc., et al., Case No. 1:21-cv-3775). Specifically, the complaint challenges the disclosures relating to management's financial projections and the analyses of the Company's financial advisors, BofA Securities, Inc. ("BofA Securities") and Credit Suisse Securities (USA) LLC ("Credit Suisse"). Among other things, the complaint alleges that the projections should have provided a reconciliation of non-GAAP financial measures to GAAP, and that the S-4 fails to disclose details about the bankers' precedent transactions analyses and DCF analyses. The complaint seeks, among other relief, a preliminary injunction until such time as corrective disclosures are issued. The case was voluntarily dismissed on June 18, 2021. As previously disclosed in the Company's Quarterly Report on Form 10-Q for the quarterly period ended April 3, 2021, filed with the SEC on May 12, 2021, on May 4, 2021, a purported stockholder of the Company filed a complaint in the United States District Court for the District of New Jersey against the Company and its board of directors alleging violations of the federal securities laws for misleading and incomplete disclosures in the S-4 (Shirey v. Coherent, Inc., et al., Civil Action No. 2:21-cv-10698 (District of New Jersey, May 4, 2021)). Specifically, the complaint challenges the disclosures relating to the Company's and II-VI's financial projections, the analyses of the Company's financial advisors, BofA Securities and Credit Suisse, and potential conflicts of interest involving Credit Suisse. Among other things, the complaint alleges that the projections should have provided all line items used to calculate certain metrics and a reconciliation of non-GAAP financial measures to GAAP, that the S-4 fails to disclose details about the bankers' precedent transactions analyses, DCF analyses and price targets analyses and that there was insufficient disclosure regarding the relationships between Credit Suisse and either the Company or II-VI. The complaint seeks, among other relief, a preliminary injunction until such time as corrective disclosures are issued. The case was voluntarily dismissed on August 2, 2021.

The case was voluntarily dismissed on July 8, 2021. Income Tax Audits We are subject to taxation and file income tax returns in the U.S. federal jurisdiction and in many state and foreign jurisdictions. Our most significant tax jurisdictions are the U.S. and Germany. For U.S. federal and German income tax purposes, all years prior to fiscal 2018 and 2011, respectively, are closed to examination. In our other major foreign jurisdictions and our major state jurisdictions, the years prior to fiscal 2015 and 2017, respectively, are closed. Earlier years in our various jurisdictions may remain open for adjustment to the extent that we have tax attribute carryforwards from those years. In October 2021, we received a final audit report for our entities that were under audit in Germany for the years 2011 through 2016. The German tax authorities issued transfer pricing adjustments related to various intercompany transactions with our South Korean and Singapore entities. The adjustments related to transactions with our South Korean entity are being appealed and contested through the Competent Authority process with South Korea. The South Korean tax authorities had previously performed an audit focused on intercompany transfer pricing arrangements for fiscal years 2014 through 2017 related to our German and U.S. entities. In May 2019, they issued transfer pricing assessments for taxes, royalties and sales commissions and we are appealing and contesting these amounts through the Competent Authority process between South Korea, Germany and the United States. Accordingly, there is no change to our tax position at the time of filing of this annual report. We are continuing to monitor and evaluate this situation. In October 2020, the South Korean tax authorities also commenced an internal review of our initial and second High-Tech tax exemptions approved in fiscal 2013 and 2016, respectively. In March 2021 we agreed with the tax authorities change in timing for claiming the tax exemption benefits. The timing and the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. Management believes that it has adequately provided for any adjustments that may result from tax examinations. We regularly engage in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. Although the timing of resolution, settlement and closure of audits is not certain, we do not believe it is reasonably possible that our unrecognized tax benefits will materially change in the next 12 months. Other Tax Matters From time to time, we are subject to review, audit or other examination related to taxes other than income taxes. While we are not currently subject to any such matters which we expect to have a material adverse effect on our financial condition and operating results, it is possible that an adverse final conclusion to any such other tax matters could lead to a material adverse effect on our financial condition and operating results.

In the normal course of business, we enter into agreements that contain a variety of representations and warranties and provide for general indemnification. Exposure under these agreements is unknown because claims may be made against us in the future and we may record charges in the future as a result of these indemnification obligations. As of October 2, 2021, we did not have any material indemnification claims that were probable or reasonably possible.

We maintain commitments to purchase inventory from our suppliers as well as fixed assets, services and other assets in the ordinary course of business. As of October 2, 2021, we had total estimated significant purchase commitments for inventory of approximately $63.8 million and significant purchase obligations for fixed assets and services of $50.6 million.

Although we do not expect that such claims and litigation will ultimately have a material adverse effect on our consolidated financial position, results of operations or cash flows, an adverse result in one or more matters could negatively affect our results in the period in which they occur, or in future periods.

The United States and many foreign governments impose tariffs and duties on the import and export of certain products we sell and purchase. From time to time our customs compliance, product classifications, duty calculations, and payments are reviewed or audited by government agencies. Any adverse result in such a review or audit could negatively affect our results in the period in which they occur, or in future periods.

German authorities are currently investigating an export compliance matter involving one of our German subsidiaries involving four former employees (whose employment was terminated following our discovery of this matter). While under German law the subsidiary can be held liable for certain infringements by its employees of German export control laws we believe that this matter involves less than approximately 1.5 million Euros in transactions in the period currently under investigation and do not believe that the final resolution of this matter will be material to our consolidated financial position, results of operations or cash flows. However, the German government investigation is ongoing and it is possible that substantial payments, fines, penalties or damages could result. Even though we do not currently expect this matter to be material to our consolidated financial position, results of operations or cash flows, circumstances could change as the investigation progresses.

In October 2021, we received a final audit report for our entities that were under audit in Germany for the years 2011 through 2016. The German tax authorities issued transfer pricing adjustments related to various intercompany transactions with our South Korean and Singapore entities. The adjustments related to transactions with our South Korean entity are being appealed and contested through the Competent Authority process with South Korea. The South Korean tax authorities had previously performed an audit focused on intercompany transfer pricing arrangements for fiscal years 2014 through 2017 related to our German and U.S. entities. In May 2019, they issued transfer pricing assessments for taxes, royalties and sales commissions and we are appealing and contesting these amounts through the Competent Authority process between South Korea, Germany and the United States. Accordingly, there is no change to our tax position at the time of filing of this annual report. We are continuing to monitor and evaluate this situation.

The timing and the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. Management believes that it has adequately provided for any adjustments that may result from tax examinations. We regularly engage in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. Although the timing of resolution, settlement and closure of audits is not certain, we do not believe it is reasonably possible that our unrecognized tax benefits will materially change in the next 12 months.

From time to time, we are subject to review, audit or other examination related to taxes other than income taxes. While we are not currently subject to any such matters which we expect to have a material adverse effect on our financial condition and operating results, it is possible that an adverse final conclusion to any such other tax matters could lead to a material adverse effect on our financial condition and operating results.
