Photodigm is the world’s leading specialist manufacturer of single frequency laser diodes for precision applications. Their monolithic laser diode products deliver unsurpassed performance for atom optics, non-linear optics, precision instruments, and high speed pulsed operation where single frequency operation is critical. The degree of performance in their products can only be achieved by focusing on their customers, and then projecting their requirements onto the semiconductor in their own wafer fabrication facility. Since 2000 they have specialized in Distributed Bragg Reflector (DBR) technology. Their proprietary tool set and extensive know-how in DFB and DBR laser design and fab has resulted in instrument quality lasers with industry-leading performance. Their monolithic design incorporates passive gratings and single growth to achieve the industry’s highest power, reliability, and overall performance. They are available certified to precise wavelengths for use in the most demanding applications in spectroscopy, metrology, and analysis.
