Technical content

The Coherent SES22-9xx-01 single emitter laser diode series has been designed to provide highest output power and efficiency for 200μm core fiber pump configurations for 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. FEATURES APPLICATIONS

  • 190 μm wide emitter
  • 22 W operating power (p-side down mounted)
  • Highly reliable single quantum well structure
  • Standard wavelength at 915 and 975 nm (other available
  • on request)
  • RoHS compliant
  • Fiber laser pumping
  • Material processing
  • Medical
