LUTTERWORTH, England, Nov. 2, 2010 — The Rio Grande high-power, single-frequency laser module is now available from AMS Technologies. It combines Rio’s high-performance external cavity laser (ECL) with a high-performance low-noise EDFA.

Developed to provide end users with robust solutions for harsh environments in easy-to-use form factors, it is suitable for usage in acoustic and interferometric sensing, lidar, high-resolution metrology, and RF and microwave photonics applications.

The laser module provides 0.1 to 1 W of optical power from 1530 to 1565 nm. It ensures reduced sensitivity to mechanical and acoustic vibrations, and can withstand harsh environment condition while preserving low power consumption and system heat dissipation.

It is based on Rio’s proprietary planar technology and consists of a gain chip and a planar lightwave circuit, including waveguide with Bragg grating, forming a laser cavity with significant advantages. It features very narrow spectral linewidth, low phase and frequency noise, low RIN and high stability and reliability.

GLOSSARY
Bragg grating
A filter that separates light into many colors via Bragg's law. Generally refers to a fiber Bragg grating used in optical communications to separate wavelengths.
laser cavity
A means of optical confinement intended to increase the gain length of radiation prior to emission from the device. The means of optical confinement used to increase gain path length vary depending upon the properties of the beam desired within the lasing medium. High light intensities occur within a laser cavity and dielectric mirrors coated for the lasing wavelength are used.The position and curvature of the optical cavity elements may be altered in order to optimize the laser performance as...
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.
metrology
The science of measurement, particularly of lengths and angles.
noise
The unwanted and unpredictable fluctuations that distort a received signal and hence tend to obscure the desired message. Noise disturbances, which may be generated in the devices of a communications system or which may enter the system from the outside, limit the range of the system and place requirements on the signal power necessary to ensure good reception.
