Request InfoWith High-Efficiency Epitaxy BarsCoherent Inc.SANTA CLARA, Calif., April 28, 2005 -- Coherent's newest fiber array package (FAP) diode lasers, now available at 940 nm and 980 nm, produce 40 W of CW power through an 800-µm fiber bundle, with a numerical aperture of <0.11. The lasers are conduction cooled and produce a wall-plug efficiency of >50 percent, significantly higher than the 35-percent efficiency of earlier generation FAPs. This FAP is first in a series of high-brightness products that utilize high-efficiency epitaxy bars. High efficiency lowers the power supply requirements of the FAP itself, resulting in reduced...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 1/30/2023Pump Laser DiodesPump laser diodes from Coherent Corp. feature a high output power of 50 W from a single chip for fiber lasers.
