120W 9xx nm High Power Laser Diode Bar on Microchannel Cooler
The Bookham BAC120C-9xx-01/02 50% fill factor laser diode bar on microchannel cooler series has been designed to provide the increased brightness and reliability required for pumping next generation solid-state disk and fibre lasers, and for direct applications. The proprietary E2 front mirror passivation process, developed at our Zurich site, prevents Catastrophic Optical Damage (COD) to the laser diode facet even at extremely high output powers. The laser diode bars are mounted on an expansion matched CuW submount onto a water-cooled microchannel package providing very high reliability in CW and pulsed (1-Hz type) applications.
