1550nm single-band narrow linewidth CW fiber laser
The single-band narrow linewidth fiber laser adopts the DFB laser cavity structure of rare earth doped fiber, and outputs a single longitudinal mode laser with a wavelength of 1550nm, a spectral linewidth of less than 3kHz, an output spectral edge-mode rejection ratio of more than 60dB, and a typical output power of 50mW, and a higher power version is available. Available in modules or benchtop packages, it is an ideal laser source for applications such as distributed sensing.
