Data Sheet
LBA-01 806nm Microchannel Cooler Based
Lateral Laser Diode Bar Arrays
LBAxxxC-806-01
The Bookham LBA-01 microchannel cooler based lateral laser
diode bar array series has been designed to provide the high
output power and high reliability required for side pumping of
Nd:YAG solid-state lasers. 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:
• Horizontally arranged laser diode bars
• Active microchannel cooler (water-cooled)
• 50W operating power per bar
• Highly reliable single quantum well MBE structure
• Telecom-grade AuSn mounting technology
• Custom assembly options available
• RoHS compliant
Applications:
• Solid-state laser pumping
• Direct applications such as material processing
• Illumination
