PH780DBR Mercury

Photodigm PH780DBR Mercury 780 nm DBR laser

This monolithic laser diode incorporates a distributed Bragg reflector (DBR) for stable frequency performance over its life time. It comes in the Mercury TOSA  compact cubic package (5.8mmWx5.2mmHx10mm) specialized for cooled laser operation.   It provides a diffraction limited, single lateral and longitudinal mode beam. Facets are passivated for high reliability. Applications for the 780 nm DBR Laser Diode include atomic spectroscopy for rubidium-based application.

  • DBR Single-Frequency Laser Chip
