Request InfoCoherent Inc.Coherent Inc., Semiconductor Group, has developed aluminum-free laser diodes that operate at more than 60 °C. These InGaAsP bars, which maintain high electrical-to-optical efficiency, have narrow spectral emission and low beam divergence, making them suitable for diode-pumped solid-state avionics platform lasers and medical and industrial applications. They were tested at 50 W in quasi-continuous-wave mode at 808 nm in temperatures up to 75 °C. Results showed <9% degradation after 109 400-µs pulses at 55 W peak power. At 60 W, the 30% fill-factor bar had a spectral width of...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/8/2023Line LampThe DELOLUX 301 line lamp from Delo Industrial Adhesives cures adhesives and other multi-functional polymers with easily integration into production systems.
