TeraXion Inc.Request Info
 
TeraXion Inc. has introduced compact versions of its distributed-feedback PS-LM and narrow-linewidth PS-NLL PureSpectrum specialized semiconductor laser modules. The company says that the new package is more than six times smaller and five times lighter and that it consumes two times less power than the original PS-NLL version. Developed for integration into OEM instrumentation, it measures 20 x 64 x 90 mm and operates over a temperature range from —5 to 55 °C. Both lasers offer a side mode suppression ratio of >30 dB, a polarization extinction ratio of >17 dB and frequency modulation amplitude of ±2.5 GHz. Applications include lidar and remote sensing, coherent sensors in oil and gas operation, perimeter and submarine detection for security, test and measurement, and coherent optical time-domain reflectometry.

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.
remote sensing
Technique that utilizes electromagnetic energy to detect and quantify information about an object that is not in contact with the sensing apparatus.
