About Photodigm

Photodigm is the world’s leading specialist manufacturer of laser diodes for precision applications. Our 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 our products can only be achieved by focusing on our customers, and then projecting their requirements onto the semiconductor in our own wafer fabrication facility.  

Since 2000 we have specialized in Distributed Bragg Reflector (DBR) technology. Our proprietary tool set and extensive know-how in laser design and fab has resulted in industry-leading performance.  Our monolithic design incorporates passive gratings and single growth epi 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.  .  

Building on our expertise in precision lasers, we expanded our product line in 2008 though the introduction of our Versatile Laser Test System for semi-active laser seekers.  In 2012 we are introducing our newest model, the LTS 1200, a fully computer controlled system delivering up to 300 watt pulses for factory floor testing.
