Request InfoBlue Sky ResearchSemiconductor lasers for 635 nm in 5-, 10- and 15-mW models have been launched by Blue Sky Research. The BRLD-635 series devices require a low operating current and operate at a wide temperature range. They have an estimated mean time to failure of 10,000 h at 50 °C, or 150,000 h at 25 °C. They are packaged in hermetically sealed DVD-grade 5.6-mm TO cans with an integrated monitor photodiode. The lasers are applicable for construction and alignment equipment, biomedical and metrology instrumentation, and bar-code readers.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 9/18/2023CMOS VCSEL DriversThe Dove 800D and 410D PAM4 digital signal processors ICs from Credo were manufactured to address the increasing bandwidth requirements of hyperscale customers, AI backend clusters, and general...Photonics Spectra November 2023 IssueAmplifier and Laser DriverThe FiberEdge® GN1816 and GN1848 from Semtech are linear transimpedance amplifiers and laser drivers, respectively, for short reach 400 g and 800 g data center applications.
