Photodigm PH770DBR 770 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 770 nm DBR Laser Diode include spectroscopy for potassium-based application.
