920nm Laser Diode

Description
The IDP920DBR 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 920 nm laser diode include spectroscopy, difference frequency generation, and low power DPSS replacement.  It can be ordered to a specific wavelength target for frequency doubling to specific trapping wavelengths.
