BAC50C-806-01 - Bookham Technology, Inc.

Data Sheet

The Bookham BAC50C-806-01/02 laser 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 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)

• 50W operating power

• Highly reliable single quantum well MBE structure

• Telecom grade AuSn mounting technology

• Assembly option with Cu base and cover

• RoHS compliant

Applications:

•Solid state laser pumping

•Direct applications such as material processing

• Printing

• Medical
