The Bookham BAC80C-9xx-01/02 50% fill factor laser diode
bar on microchannel cooler series has been designed to
provide the high brightness and reliability required for pumping
solid-state 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.
Features:
• Mounted 10mm x 1.2mm laser diode bar
• Active microchannel cooler (water-cooled)
•80W operating power
•Highly reliable single quantum well MBE structure
•Telecom grade AuSn mounting technology
•Assembly option with Cu base and cover
•Standard wavelengths at 915nm, 940nm, and 980nm
(others available on request)
• RoHS compliant
Applications:
•Solid-state and fiber laser pumping
• Direct applications such as material processing
•Printing
• Medical
