PH895DBR Mercury

Photodigm PH895DBR Mercury 895 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 895 nm DBR Laser Diode include mobile spectroscopy instrumentation where durability and reliability are essential.
