Photodigm PH852DBR 852 nm DBR laser

This monolithic laser diode incorporates a distributed Bragg reflector (DBR) for stable frequency performance over its life time. It provides a diffraction limited, single lateral and longitudinal mode beam. Facets are passivated for high reliability. Applications for the 852 nm DBR Laser Diode include atomic spectroscopy for cesium based applications and fiber optics telecommunications.

  • DBR Single-Frequency Laser Chip
  • AlGaAs QW Active Layer
  • Facets passivated to withstand high power without catastrophic optical damage (COD)
  • Epi designed for high reliability
  • Wavelength tunable across 2 nm around the Cs line
  • Pulsed operation for spectral stability at short pulse lengths
  • High power for CW applications
  • High Slope Efficiency

Available packages : chip-on-submount, C-mount, TO-8, butterfly
