Photodigm Inc.The Photodigm family of high-power edge-emitting Distributed Bragg Reflector (DBR) laser diodes is based on Photodigm’s proprietary single epi growth DBR laser architecture. The Photodigm DBR laser architecture consists of an electrically pumped gain region and a separate passive DBR grating region, monolithically fabricated over a continuous ridge waveguide. This design has resulted in the world’s highest power commercially available, single-frequency, monolithic laser diodes with performance specifications that rival bench-top research lasers. Over the years, Photodigm DBR lasers have proven themselves to be ideally suited for applications requiring high-power single-frequency performance within a well-defined operating range. Photodigm has worked with its customers to develop a family of laser products unmatched in the industry. Optimized for stability, reliability, and power efficiency, these devices have opened up opportunities for an emerging class of cost-effective precision mobile instruments for applications in spectroscopy, atomic physics, non-linear optics, and quantum information. The DBR laser is often compared to the distributed feedback, or DFB laser diodes.
