50W 9xxnm 30% Fill Factor High Power Laser Diode
Bar on Passive Cu Block Cooler
BPC50C-9xx-01
The Bookham BPC50C-9xx-01 30% fill factor laser diode bar
on passive cooler series has been designed to provide the high
brightness and and reliability required for both collimated 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 Cu block package providing very high reliability in CW
and pulsed (1-Hz type) applications.
Features:
• Mounted 10mm x 1.2mm laser diode bar
• Passive 1" x 1" Cu block cooler
• 30% fill factor (150µm emitter / 500µm pitch)
• 50W operating power
• Highly reliable single quantum well MBE structure
• Telecom grade AuSn mounting technology
• Standard wavelengths at 915nm, 940nm, and 980nm
(others available on request)
• RoHS compliant
Applications:
• Collimated solid-state laser pumping
• Direct applications such as material processing
• Printing
• Medical
