Photodigm DBR Laser with Beam Correction

For a decade now, Photodigm has worked with leading researchers worldwide to deliver monolithic, single frequency laser diodes for the most demanding requirements.Our laser design and wafer fabrication engineers have consistently improved the performance of our devices. During this time, our users have seen higher powers, lower threshold currents, and higher slope efficiency compared to earlier generations of product. Users are reporting Gaussian linewidths below 500 kHZ, comparing favorably with commercial ECDLs and almost an order of magnitude lower than competing DFB lasers. With the introduction of our advanced Mercury­™ TOSA in 2012, shown in Fig. 1, Phogodigm lasers set the standards for spectroscopic laser diodes for research and industry.
