SAXONBURG, Pa., Jan. 16, 2026 (GLOBE NEWSWIRE) — Coherent Corp. (NYSE: COHR), a global leader in photonics, today announced the release of a new electro-optic modulator (EOM) designed for high-speed switching of CO\u2082 lasers in via drilling applications for the semiconductor industry. The new EOM provides a germanium-free solution capable of sub-microsecond pulse generation at laser powers up to 300W, addressing both performance demands and supply-chain constraints.<\/p>\n
The Coherent EOM is the only germanium-free ultra-fast switching solution on the market capable of producing pulses shorter than 1\u00b5s with sub-200ns rise and fall times. By eliminating dependence on germanium while delivering high speed and power handling, the EOM establishes a new benchmark for precision laser modulation in via drilling.<\/p>\n
Via drilling remains a critical segment of semiconductor manufacturing, yet the scarcity of germanium has made traditional acousto-optic modulators (AOMs) increasingly expensive and difficult to source. Coherent\u2019s EOM addresses this challenge with a germanium-free architecture that delivers higher power handling, shorter pulse capability, and faster switching performance than conventional AOM-based solutions. Simplifying system design and installation, EOM\u2019s enable straight through alignment, eliminating diffractive order beam angles of conventional AOM-based solutions. There are currently no comparable EOM alternatives available for this market.<\/p>\n
\u201cCoherent has been developing electro-optic modulators for more than 50 years,\u201d said Steve Rummel, Sr. Vice President at Coherent. \u201cThis EOM represents a significant step forward for the via drilling market, delivering ultra-fast switching performance at a more accessible price point while removing dependence on scarce materials at a time when supply security is critical. Our ability to replace the scarcity of germanium with an alternative is the perfect time for the market.\u201d<\/p>\n
Coherent is launching a fully featured 300W version of the EOM, with a 1,000W version available for alpha prototype testing. The EOM pairs seamlessly with Coherent CO\u2082 lasers and Coherent F-Theta lenses, enabling efficient delivery of maximum pulse energy with industry-leading precision and performance. This release represents version 2.0 of Coherent\u2019s EOM platform, featuring improved reliability and ease of use compared to the previous generation. <\/p>\n
