8W 940nm Uncooled Multimode Laser
Diode Module
MU8-940-01/04
The Bookham new MU8-940-01/04 multimode laser diode
module series has been designed to provide the increased
power and reliability required for pumping next generation solid-
state and fiber lasers, and for direct applications. The module
wwwin.cDlaudtaeSsheaet4mUu.cltoimmode laser diode chip with E2 front mirror
passivation that prevents Catastrophic Optical Damage (COD)
to the laser diode facet even at very high power levels. The
coupling process allows for high output powers that are very
stable with both time and temperature.
Features:
• High output power of 8W
• 0.22NA 105µm core multimode fiber pigtail
(0.15NA upon request)
• Hermetically sealed 3-pin and 2-pin packages
• Floating anode/cathode
• High reliability
• Excellent solderability
• Standard wavelengths at 940nm
• RoHS compliant
Applications:
• Fiber laser pumping
• Direct applications
• Material processing
• Printing
• Medical
