Ultranarrow Linewidth Fiber Laser UNL
For fiber sensing, the UNL series fiber laser offers narrow linewidth, long coherence length, low noise and resistance to environmental interference. Distinctive optical paths with precision drive and control eliminate external temperature and vibration effects on wavelength, enabling stable single-longitudinal-mode, ultranarrow-linewidth single-frequency output. Serial-port configuration, high integration, compact size and easy debugging are provided. Single-mode or PM fiber output can be customized.
