Single-Frequency, 1,064-nm Laser Designed for Space LIDAR

Redfern Integrated Optics was awarded a Phase 2 Small Business Innovation Research (SBIR) contract for further development of its single-frequency, narrow- linewidth semiconductor laser technology in the 1,064-nm spectral region, suitable for spaceflight operation. The external-cavity semiconductor laser is packaged in a standard 14-pin compact “butterfly” package, and produces a single- frequency output with a linewidth less than 2 kHz, ultra-low phase and relative intensity noise, and high immunity to vibrations, all under a wide range of operating temperatures.
