9 W 9xx nm 90 μm High Power Single Emitter Laser Diode on Submount

Product image of 9 W 9xx nm 90 μm High Power Single Emitter Laser Diode on Submount

The Coherent SES9-9xx-01 single emitter laser diode series has been designed to provide the high output power, high coupling efficiency and high reliability required for pumping next generation fiber lasers and for other high power laser diode 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 single emitter laser diodes are p-side down mounted on an optimized submount providing very low thermal resistance
