HI-Q® LASER LINEWIDTH/PHASE NOISE ANALYZER

Using a homodyne methodology, HI-Q® Laser Linewidth / Phase Noise Analyzer offers a fully automated measurement of ultra-low phase noise CW laser sources.

​

HI-Q® Laser Linewidth / Phase Noise Analyzer is capable of rapidly measuring laser phase noise and estimating its FWHM linewidth down to < 3 Hz without complex setup or reference lasers normally required to make such a narrow linewidth measurement.

This homodyne-based system is unique in wideband measurement without requiring another low noise reference laser source. The complete system operates with ease, speed and precision via a simple graphic user interface on an embedded PC accessible via user supplied eternal PC or monitor/keyboard/mouse. No additional test equipment required. The unmatched ultra-low phase/frequency noise analyzer is scalable to various input wavelength bands and is available with low relative intensity noise (RIN) measurement option.
