Low Phase Noise Narrow Linewidth External Cavity Lasers

Pressemitteilung   •   Jun 07, 2011 13:48 CEST

RIO´s PLANEXTM laser consists of a gain chip and a prorietary Planar Lightwave Circuit (PLC) that includes a Bragg grating. The coupling of these elements forms a laser cavity with significant benefits, including narrow spectral linewidth, low phase noise and low wavelength sensitivity to bias current and temperature.

PLANEXTM lasers are an ideal source for multiple commercial and military fiber optic sensor applications, including interferometric and Brillouin DTSS systems for oil&gas, security and structural integrity. Different versions regarding wavelength, phase noise and output power are available.

RIO has also introduced a lower cost Grade 0 version for low end application
