Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES In December 2024, affiliates of Trumpf SE & Co. KG (“Trumpf”) filed patent lawsuits in two different Unified Patent Courts (UPC) located in Germany against IPG Laser GmbH & Co. KG alleging infringement of two patents granted by the European Patent Office by the Company's adjustable mode beam (AMB) lasers. In January 2026, the Company filed a complaint against Trumpf in the U.S. District Court for the Eastern District of Texas alleging infringement of one U.S. Patent which covers IPG’s safety‑control electronics invention. On February 25, 2026 and March 16, 2026, the UPC courts upheld the validity of the Trumpf patents and ruled that the Company’s AMB lasers infringed the two patents asserted in the UPC cases. IPG and Trumpf entered into a settlement agreement effective May 1, 2026 under which IPG will make a lump sum payment of $13,500 to Trumpf and license from Trumpf the two patents worldwide in exchange for a royalty. Also under the settlement, Trumpf agreed to withdraw the judgments, and the Company agreed to dismiss its complaint against Trumpf in the Texas matter and withdraw challenges to the two Trumpf patents. The settlement provides additional evidence regarding conditions existing as of March 31, 2026 and therefore the Company has accrued the cost to settle these matters in Accrued expenses and other current liabilities on the Company's Condensed Consolidated Balance Sheets as of March 31, 2026. The cost of the settlement is reflected in Settlement of litigation matters in the Company's Condensed Consolidated Statements of Operations for the three months ended March 31, 2026, whereas the royalty charges are reflected in Cost of sales. From time to time, the Company may be involved in legal disputes and other proceedings in the ordinary course of its business. These matters may include allegations of infringement of intellectual property, commercial disputes and employment matters. As of March 31, 2026 and through the filing date of these Condensed Consolidated Financial Statements, the Company is aware of no additional ongoing legal proceedings that management estimates could have a material effect on the Company's Condensed Consolidated Financial Statements. Effective January 1, 2025, the Company is self-insured for employee medical benefits in the United States. The employee medical obligations are managed by a third-party provider and the Company has accrued $3,006 and $3,024 related to this arrangement in Accrued expenses and other current liabilities within the Consolidated Balance Sheet as of March 31, 2026 and December 31, 2025, respectively. To limit the Company’s potential liabilities for these risks, the Company purchases insurance from a third party that provides stop-loss protection for medical costs in the United States that exceed $225 per person per annum. The Company provides product warranties on its lasers, laser and non-laser systems, and amplifiers. Refer to Note 8, "Product Warranties" for information related to the Company's warranty accrual.
