Operating within a wavelength range from near UV (390nm) to green (535nm), this technology marks a significant advancement in single-frequency light sources. Its flexible design ensures exceptional control and stability across various wavelengths, with narrow line widths at different output power levels.

The DFB LD, the first in the company’s portfolio, operates in a single transverse mode with a 450nm emission wavelength. It is undergoing life-testing at 30-50 mW power levels, having shown excellent stability with minimal degradation after over 1,500 hours of continuous operation.

The company claims to provide a range of advanced single-frequency lasers in various formats designed for Spectroscopy, Communication, Quantum, Sensing, Ranging, and Holography applications. Available options include uncooled TO-can modules and temperature-controlled units with fiberized or free-space collimated outputs.

“We are excited to bring this revolutionary laser technology to the market,” said Philipp Vorreau, General Manager at EXALOS. “Our proprietary design not only delivers superior wavelength control and stability but also provides unparalleled versatility for applications requiring high wavelength precision and reliability.”
