The narrow linewidth single frequency fiber laser is a kind of low noise fiber lasers with output linewidth at kHz level, has ultra-low frequency noise and intensity noise, and the side-mode suppression ratio (SMSR) is over 50dB. The output power can reach 100mW, and higher output power can be provided per your specific needs. The wavelength tunable range is from 1900nm to 2050nm, e.g. 1908nm, 1940nm, 1950nm, 2004nm, 2050nm, etc.
Besides, high-intensity package is adopted to allow that the fiber laser is applicable to various environments, ensuring stable single longitudinal mode output and free of mode-hops even under changing environmental conditions such as temperature variance, vibrating and impacting, etc.
