DBR Single-Frequency Laser Chip
AlGaAs QW Active Layer
Epi designed for high reliability
Available in several package styles
Pulsed operation for spectral stability at short pulse lengths
High power for CW applications
High Slope Efficiency
Spectroscopy Series 780 nm laser diode certified for D2 line of Rb
The PH780DBR Series of high-power edge-emitting lasers are based on Photodigm’s
advanced single-frequency laser technology. It provides a diffraction limited, single lateral and longitudinal mode beam. Facets are passivated for high-power
reliability. Single frequency 780 nm laser diodes are used in atomic spectroscopy for rubidium-based applications.

Handling Precautions
These devices are sensitive to ESD. When handling the module, grounded work area and wrist strap must be used. Always store in an antistatic container with all leads shorted together.
How To Order
Part number example: PH780DBR080CM. Assign optical power from those available shown below.
Use a three-digit format for all power entries. Call factory for special performance selection and certification to certain atomic absorption lines. Butterfly package is offered only at 50% of output powers shown, and is not recommended for spectroscopy applications. See Photodigm’s application note titled Optical Feedback
