The Bookham BAC40C-806-01/02 30% fill factor laser diode
bar on microchannel cooler series has been designed to
provide the high output power and high reliability required for
both solid-state laser pumping and 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)
• 30% fill factor (150µmemitter / 500µmpitch)
• 40W operating power
• Highly reliable single quantum well MBE structure
• Telecom grade AuSn mounting technology
• Packaging option with Cu base and cover
• RoHS compliant
Applications:
• Collimated solid state laser pumping
•Direct applications such as material processing
• Printing
• Medical
