Request InfoYellow semiconductor lasersCoherent Inc.SANTA CLARA, Calif., April 16, 2009 – Coherent Inc. has unveiled the Sapphire 561 series yellow optically pumped semiconductor lasers. Available with 50, 75, 100 or 150 mW of output power in a TEM00 beam with M2 <1.1, they produce noise of <0.25% rms from 20 Hz to 2 MHz. The company says that the devices deliver four times better electrical efficiency and lower heat dissipation than products based on legacy Nd:YAG technology. Operating at 561 nm and measuring 125 × 70 × 34 mm, the lasers share the same compact form factor and all interface and operating characteristics as the Sapphire 488 models, which simplifies...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 Issue1200-mW Pump Laser ModuleThe 1200-mW pump laser module from Coherent was made for optical amplification in DWDM networks in a 10-pin butterfly package.
