Laser Linewidth Analyzer

The Optilab laser linewidth analyzer is based on the delayed self-heterodyne interferometric technique. It consists of a high-performance LiNbO3 phase modulator as the frequency shifter in the delayed self-heterodyne interferometer. It also includes high-gain photoreceiver and RF amplifier, as well as a high-resolution spectrum analyzer for accurate and convenient measurement. The high sensitivity allows measurement and analysis of lasers with intrinsic linewidth of several kHz.
