# Coherent launches 18W laser diode for DPSS laser pumping

SAXONBURG, Pa. - Coherent Corp. (NYSE: COHR), a technology company showing strong revenue growth of 21.67% in the last twelve months, has introduced a new high-power laser diode designed for pumping diode-pumped solid-state (DPSS) lasers, according to a press release issued Friday. According to InvestingPro data, the company maintains healthy liquidity with current assets more than double its short-term obligations.

The SES18-880A-190-10 delivers 18 watts of optical output power with over 62% conversion efficiency and 97% polarization extinction ratio. The 880 nm single-emitter laser diode features a 190 µm emitter and is built on the company’s 6-inch GaAs wafer platform.

The new product targets applications in micromachining, advanced packaging, and semiconductor processing where beam quality and power scalability are critical requirements.

"This new diode allows customers to realize the full benefits of 880 nm pumping—delivering lower quantum defects, reduced thermal lensing, and enhanced mode quality compared to traditional 808 nm solutions," said Dr. Karlheinz Gulden, Senior Vice President of Laser Components and Subsystems at Coherent.

The laser diode is compatible with Volume Bragg Grating stabilization for precise wavelength control. Coherent also offers variations at 878, 885, and 888 nm wavelengths to support different DPSS gain media, as well as fiber-coupled modules using the same chip technology.

The company manufactures the product through a vertically integrated process that includes epitaxial wafer growth, chip design, and sub mount packaging.

The SES18-880A-190-10 is currently available for general purchase. Coherent will showcase the product at Laser World of Photonics in Munich from June 24-27.

In other recent news, Coherent Corp. has introduced a new diamond-loaded silicon carbide ceramic composite aimed at enhancing thermal management in AI datacenters and high-performance computing systems. The material boasts isotropic thermal conductivity exceeding 800 W/m-K, which is double that of copper, offering significant improvements in thermal efficiency. This development comes as the company continues to expand its portfolio of engineered materials.

In financial updates, several analyst firms have adjusted their outlooks on Coherent. JPMorgan raised its price target for Coherent to $100, citing confidence in the company’s growth and margin trajectory, with projections of 10% revenue growth in fiscal years 2026 and 2027. Meanwhile, Citi increased its price target to $115, highlighting Coherent’s focus on core businesses and profitability improvements. Stifel and Rosenblatt Securities also maintained their Buy ratings, with price targets of $100 and $95, respectively, reflecting positive sentiment toward Coherent’s strategic direction and market positioning.

Coherent’s recent Analyst/Investor Day provided insights into its long-term strategy, emphasizing growth in the Datacenter and Communications and Industrial sectors. The company aims for a compound annual growth rate of 10%-15% in revenue over the next few years. Management has outlined goals for enhancing profitability through increased revenue volume, optimized pricing, and reduced costs, with targets of gross margins over 42% and operating margins over 24%.
