795nm Laser Diode
Description
The IDP795DBR Series of high-power
edge-emitting lasers are based on Idealphotonics’s advanced single-frequency
laser technology. It provides a diffraction limited, single lateral and
longitudinal mode beam. Facets are passivated for high-power reliability.
Applications for the 795 nm Laser Diode include rubidium-based D1 applications.
Feathure
Available in several package styles
Pulsed operation for spectral stability at short pulse lengths
High power for CW applications
High Slope Efficiency
Technology
DBR Single-Frequency Laser Chip
AlGaAs QW Active Layer
