1550nm 100mW 100kHz Narrow-Linewidth PM Fiber Laser Source Benchtop NLSL-1550-100-PM-B
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. The spectral linewidth is less than 100kHz. The single-mode or polarization-maintaining fiber coupling output is available in module or desktop packaging. Cost-effective laser source for distributed sensing.
[Features]
