Product information "SESx High-power Laser Diodes"

Single Emitter, Submount; 803 to 975 nm; Spectral Width 2, 4 nm; Output Power 4-9 W CW; Threshold Current 0.5-1.2 A; Slope Efficiency 1.0, 1.1 W/A

II-VI Incorporated has designed the SESx series of single-emitter high-power laser diodes on submount to provide the high output power, high coupling efficiency and high reliability required for pumping solid-state and next generation fiber lasers as well as direct laser and other high-power laser diode applications.

SESx series laser diodes are available in three versions:

  • SES4-808A/B/C-01: 4 W, 808 nm, 90 µm wide emitter
  • SES8-808A/B/C-01: 8 W, 808 nm, 190 µm wide emitter
  • SES9-9xx-01: 9 W, 9xx nm, 90 μm wide emitter

The proprietary E2 front mirror passivation process, developed at II-VI Incorporated’s 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.
