Coherent Unveils 300W Germanium-Free EOM with Sub-200ns Switching

COHRCOHR

Coherent released a germanium-free electro-optic modulator delivering sub-microsecond pulses at up to 300W for CO₂ laser via drilling with sub-200ns rise/fall times, removing germanium scarcity constraints. A 300W model is available now, with a 1,000W prototype in alpha testing to boost semiconductor manufacturing precision.

1. Coherent Unveils AxioView™ Imaging Fiber Assemblies for Medical Catheters

Coherent launched its AxioView™ imaging fiber assemblies on January 16, 2026, targeting OCT, NIRS and multimodal catheter applications in cardiovascular, neurovascular and gastrointestinal procedures. Engineered to deliver high-resolution imaging in minimally invasive platforms, AxioView™ supports ball-tip, side-fire and chisel distal geometries, and is manufactured under ISO 13485 certification. The product leverages Coherent’s vertically integrated fiber production in Saxonburg, Pennsylvania, enabling customers to scale from prototype to volume production with consistent optical performance. Initial customer evaluations begin this month at Photonics West 2026, positioning Coherent to capture a share of the estimated $1.2 billion medical photonics catheter market by 2028.

2. Introduction of Germanium-Free Electro-Optic Modulator for CO₂ Laser Via Drilling

On the same date, Coherent announced a new electro-optic modulator (EOM) optimized for high-speed switching of CO₂ lasers in semiconductor via drilling. This germanium-free device generates sub-microsecond pulses at up to 300 W, with rise/fall times below 200 ns, eliminating reliance on scarce germanium and reducing raw-material costs by an estimated 25%. The 300 W model is available for immediate order with standard lead times, while a 1,000 W version enters alpha testing next quarter. By simplifying system alignment and achieving straight-through beam delivery, Coherent aims to displace legacy acousto-optic modulators and address the $450 million laser drilling components segment.

3. Sapphire XT Expands Visible Laser Platform for Life Science and Semiconductor Innovations

On January 15, 2026, Coherent introduced Sapphire XT, a compact 1 W visible laser offering wavelengths at 488 nm, 532 nm and 561 nm, each with integrated modulation via its Optically Pumped Semiconductor (OPS) technology. The device reduces form factor by over 50% compared to predecessors, while doubling throughput for super-resolution microscopy and DNA sequencing. Sapphire XT’s intrinsic electrical modulation interface removes the need for external acousto-optic modulators, cutting system costs by approximately 30%. Compatibility with Coherent’s OBIS XT platform extends coverage to 640 nm and key UV bands, enabling multi-wavelength configurations for advanced life science and semiconductor inspection systems.

4. Forbes Recognition Highlights Coherent’s Financial and Cultural Strength

Coherent was named to Forbes’ 2026 America’s Best Companies list, evaluated across 100+ metrics in financial performance, employee engagement and sustainability. The accolade reflects year-over-year revenue growth of 14%, a 120 basis point expansion in gross margins and a 96% employee satisfaction score in global surveys. CEO Jim Anderson credited the award to a culture of innovation and execution, while Coherent’s inclusion signals investor confidence in its ability to deliver consistent growth across photonics markets.
