The single-frequency narrow linewidth fiber laser uses an ultra-narrow linewidth external cavity semiconductor laser chip to output a single longitudinal mode laser with a wavelength of 1550nm, with a spectral linewidth of less than 100kHz, and a single-mode or polarization maintaining fiber coupled output. It is provided in a module or desktop package. It is a cost-effective laser source that can be used for distributed sensing.
