Product Overview
1550nm ultra-narrow linewidth laser is a self-developed low-noise fiber laser. The uniquely designed ultra-narrow fiber filter ensures single-frequency operation of the fiber laser. The output spectral linewidth can reach the level of kHz, and has ultra-low frequency noise and intensity noise.The side mode rejection ratio of the output spectrum is more than 50dB. Meanwhile, the unique temperature control technology and anti-vibration structure eliminate the influence of external temperature change and vibration on the output wavelength, so that the Narrow Linewidth Fiber Laser can realize stable single longitudinal mode and ultra-narrow linewidth of single-frequency laser output.
