The single-frequency narrow linewidth fiber laser employs a rare-earth-doped fiber DFB laser cavity structure, outputting a single longitudinal mode laser at a wavelength of 1550nm with a spectral linewidth of less than 3kHz. It features an output spectral side-mode suppression ratio exceeding 60dB, and a typical output power of 50mW, with options for higher power versions available. Offered in either module or benchtop packaging, it serves as an ideal laser source for applications such as distributed sensing.
