1064nm 50mW Ultra-narrow Linewidth Laser Source Module With PM Fiber NLFL-1064-50-T-PM-M
The single-frequency narrow-linewidth continuous fiber laser adopts a fiber DFB laser cavity structure, outputs a single longitudinal mode narrow-linewidth continuous laser in the 1064nm wavelength band, has a spectral linewidth of less than 20kHz, and an output spectral side mode suppression ratio of more than 60dB. It can also provide higher power versions. It can be provided in module or desktop packaging, and is an ideal laser source for applications such as distributed sensing.
