1.5um High Power Single Frequency Fiber Laser

Product Description:

The 1.5um high power single-frequency fiber lasers are featured by low noise and narrow linewidth. They are based on the self-developed single frequency laser basic module of Connet Laser. The high power output is achieved by multi-stage amplification and the maximum power can be up to 10W.


The 1550nm high power single frequency fiber laser of Connet Laser employs the optimized optical path to realize the high power output and suppress the nonlinear effects in the fiber effectively and meanwhile, obtain the near diffraction-limited beam quality.


The 1.5um high power single frequency fiber laseris normally with 10W output power and the other output power can be customized. The center wavelength can be chosen freely in the range of 1535-1575nm, such as the standard wavelengths of ITU.
