4W 940nm Uncooled Multimode Laser Diode Module

The Bookham MU4-940 multimode laser diode module has been designed to provide the high power and reliability required for pumping next generation high power amplifiers for CaTV and FTTx. The pump module includes a multimode 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 4W
• 0.22NA 105µm core multimode fiber pigtail
• Hermetically sealed package
• Floating anode/cathode
• High reliability
• Excellent solderability
• Standard wavelength at 940nm
• Low power dissipation
• RoHS compliant

APPLICATIONs:
• High power EDFA for CaTV and FTTx
• Er/Yb co-doped double clad pumping
