Data Sheet 4W 940nm Uncooled Multimode Laser Diode Module MU4-940-04 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 1 Operating Characteristics: Conditions unless otherwise stated: • Parameters at 25°C heat sink temperature and use of a thermal interface material rated for a thermal impedance of less than 1.3cm2 .K/W (0.2in2 .K/W) Parameter Symbol Min Fiber Coupled CW Output Power POP 4.0 Operating Current IOP 5.5 A Forward Voltage VOP 2.0 V 0.6 A Threshold Current Typ 0.5 ηP= POP /( IOP - Ith ) 0.8 0.95 λc940 930 940 Center Wavelength ∆λ Spectral Width (95% of Power) Unit W Ith Slope Efficiency Max W/A 950 nm 6 nm Absolute Maximum Ratings: Parameter Min Max Unit 500 V 85 °C Lead Soldering Temperature 250 °C Lead Soldering Time 10 sec ESD Storage Temperature -40 Operating Case Temperature 0 45 °C Relative Humidity (Operating) 5 85 % Fiber Specification: Parameter Min Typ Max Unit Buffer Diameter 230 250 270 µm Cladding Diameter 123 125 128 µm Core Diameter 102 104 106 µm 2.5 m Numeric Aperture Fiber Length Notes:  0.15NA available on request.
