| Data Sheet 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 solidstate and fiber lasers, and for direct applications. The 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 of 8W * 0.22NA 105m 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 1 Data Sheet Characteristics Conditions unless otherwise stated: Parameters at 25C heat sink temperature and use of a thermal interface material rated for a thermal contact resistance of less than 1.3cm2 K/W (0.2in2 K/W). Pigtail fiber with 105m core diameter and 0.22NA.
