Products and Services

A Complete Line of Products

Photodigm DBR laser diodes are precisely fabricated to deliver single frequency, single mode output in the near-IR spectral band from about 740 nm to 1100 nm. The ridge waveguide selects a single spatial mode, and the monolithic DBR grating selects a single longitudinal mode. With a narrow bandwidth on the order of 1 MHz, Photodigm DBR lasers are uniquely suited to applications in atom sensors, non-linear, and spectroscopy.  Since their introduction in 2008, we have sweated the details with our proprietary epi designs and our in-house wafer fab.   We fabricate our own product, setting us apart from our competition with superior reliability at the highest available power in a monolithic semiconductor.

Spectroscopy-Certified™ Semiconductor lasers

We are the recognized leader in lasers resonant with atomic and molecular transitions. Our Spectroscopy-Certified™ DBR lasers are designed for the D1 and D2 lines of K, Rb, and Cs; the He metastable line at 1083 nm, as well as for H2O at 828 nm and O2 at 760 nm. Each device is individually screened and certified to be resonant with the designated transition within the specified operating range. Unlike competing DFB lasers, Photodigm DBR lasers exhibit deterministic behavior with aging, a characteristic we call Perma-Loc™.  DFB lasers are prone to sudden, indeterminate mode hops as they age, resulting in premature end-of-life. You can be confident that the Photodigm DBR will lock to the transition throughout its life.  

Now available!! Photodigm's Mercury package  Designed for OEM's and  High Power applications.


Application-Certified™ Laser Diodes

Photodigm Application-Certified™ DBR laser diodes are no less stringently tested.  Designed for OEM applications in Raman spectroscopy, tunable diode laser absorption spectroscopy, picosecond optical pumping, and non-linear optics, they conform to strict specifications of linewidth, wavelength, spectral characteristics, and other user-defined criteria.
