Laser Linewidth/Frequency Noise Measurement System


OEwaves’ ultra-narrow Automated Laser Linewidth and Frequency Noise Measurement System u ti lizes a homodyne methodology for automated measurement capable of tes ti ng ultra-low phase noise laser sources. The user friendly test system is capable of rapidly measuring <100 Hz of Lorentzian linewidth of a laser source without the complicated setup typically required to make such a narrow linewidth measurement.

This homodyne based system is unique in wide band measurement without requiring another low noise reference laser source. The complete system operates with ease, speed and precision, and a simple graphic user interface via a tablet, without requiring any additional test equipment. The unmatched ultra-low phase/frequency noise measurement system is scalable to various input wavelengths and capable of low relative intensity noise (RIN) measurement.
