RIO Awarded Phase 2 Contract for Space Lidar

May 2012
SANTA CLARA, Calif., May 2, 2012 — Redfern Integrated Optics Inc. (RIO) was awarded a Phase 2 SBIR contract from NASA to further develop its single-frequency narrow-linewidth semiconductor laser technology in the 1064-nm spectral region for space lidar, it announced.

RIO’s proprietary 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, ultralow phase and relative intensity noise, and high immunity to vibrations, all under a wide range of operating temperatures.

“Our partnership with NASA in the development of superior laser sources for the next generation space lidar instruments has reached a new stage with this award which will enable RIO to expand its narrow-linewidth laser product line to 1064 nm,” said Dr. Radu Barsan, chairman, president and CEO of RIO.

GLOSSARY
lidar
An acronym of light detection and ranging, describing systems that use a light beam in place of conventional microwave beams for atmospheric monitoring, tracking and detection functions. Ladar, an acronym of laser detection and ranging, uses laser light for detection of speed, altitude, direction and range; it is often called laser radar.
semiconductor laser
A semiconductor material which is designed and grown for the efficient production of short wavelength stimulated emission through high gain as well as low internal losses. Materials with band gap energies which emit radiation efficiently within the desired wavelength region are used. Diodes may emit vertically in relation to the laser material junction in a VCSEL configuration or horizontally in an edge emitting configuration. Synonymous with laser diode.  Sometimes used...
