The Optilab LLA is a laser linewidth analyzer 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. The LLA also includes high-gain photoreceiver and RF amplifier, as well as a high-resolution spectrum analyzer for accurate and convenient measurement. The high sensitivity of the LLA allows measurement and analysis of lasers with intrinsic linewidth of several kHz. An intuitive and easy-to-use GUI can provide lineshape plots and Lorentzian fitting.
