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.

 Blokken 84 3460 Birkerød Denmark Quality: ISO 9000:2015 www.nktphotonics.com Social: Facebook, LinkedIn, Twitter, YouTube Tel.: +45 4348 39 00 Fax: +45 4348 39 01 |  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. See us at Laser World of Photonics in Munich, June 24–27 (booth A3.137)! |
 All wavelengths. Lochhamer Schlag 19 82166 Gräfelfing Germany Quality: ISO 9001:2015 www.toptica.com Social: Facebook, LinkedIn, YouTube E-mail: Tel.: +49 89 85 83 70 Fax: +49 89 85 83 72 00 |  All of TOPTICA’s tunable diode lasers offer a narrow linewidth of typically 100 kHz, corresponding to coherence lengths of almost 1 km. By stabilizing these lasers even further with TOPTICA’s locking electronics, linewidths below 1 Hz are possible. See us at Laser World of Photonics in Munich, June 24–27 (booth B2.103)! |
 Invent - Develop - Deliver 465 N. Halstead Street Suite 140 Pasadena, CA 91107 United States |  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. See us at Laser World of Photonics in Munich, June 24–27 (booth B2.417)! |
