Where to Buy Linewidth Measurement Equipment

The linewidth of lasers is relevant for various applications. Specialized measurement equipment can reliably measure laser linewidth and can contribute to comprehensive and helpful laser noise specifications. Different measurement techniques can be applied, e.g. spectrometers, interferometers, self-heterodyne measurement setups and beat note analysis.

The Koheras narrow linewidth, single-frequency fiber lasers are ultra-low noise sources with longitudinal single mode and single frequency operation. The lasers are based on a DFB design ensuring robust and reliable operation and are delivered as fully integrated systems for industrial and scientific applications. Koheras offers an unprecedented low phase- and intensity noise level at Yb, Er and Tm wavelengths. It has a very high stability, and mode-hop free inherent single frequency output – even when exposed to changing environmental conditions. You can also get shot noise limited solutions for applications demanding an extra low intensity noise level.

OEwaves’ HI-Q™ Optical Test Measurement System utilizes a homodyne methodology for automated measurement capable of testing ultra-low phase noise laser sources. The user friendly test system is capable of rapidly measuring <10 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 PC, without requiring any additional test equipment. The unmatched ultra-low phase/frequency noise analyzer system is scalable to various input wavelengths and capable of low relative intensity noise (RIN) measurement.
