Vescent Photonics (www.vescent.com)
Vescent Photonics, Inc. was founded in 2002 to develop and manufacture technologies in electro-optics, tunable lasers, and electronics for precision laser control. Vescent Photonics provides the highest performance non-mechanical, tunable lasers for spectroscopic sensing in emerging cold-atom applications. We also offer a line of ultra-low noise electronics for precision laser control and stabilization as well as electro-optic modules whose performance dovetails with the electronics to provide complete laser solutions ready to deliver stabilized, frequency-agile light to a wide array of Atomic, Molecular, & Optical Physics experiments.
Our patented evanescently coupled liquid crystal waveguides have the industry’s largest tunable optical phase delay available in a commercial product enabling wide angle, high resolution 2-D beam steering. These devices serve the LADAR, robotic vision, and imaging communities.
With over 50 years of combined technical expertise directly in cold-atom and liquid crystal physics as well as the photonics industry and being wholly owned by its founders, Vescent Photonics has only two goals: customer satisfaction and product performance.

Photodigm (photodigm.com)
Photodigm is the world’s leading specialist manufacturer of single spatial and longitudinal mode laser diodes. Our monolithic laser diode products deliver unsurpassed performance for atom optics, non-linear optics, precision instruments, and high speed pulsed operation where beam quality and spectral purity are critical.
Photodigm offers Spectroscopy-Certified™ DBR Lasers, Application-Certified™ DBR Lasers and SOAs and Gain Chips!
Photodigm DBR laser diodes are precisely fabricated to deliver single frequency, single mode output in the near-IR spectral band from about 740nm to 1100nm. 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.
