Lowest Price for High Reliability Edfa - 1.0um CoSF-D Narrow Linewidth Single Frequency Fiber Laser Basic Module – Connet Laser Detail:

Connet CoSF-D series high-power narrow linewidth single frequency fiber laser is a low-noise fiber laser independently developed by patented technology. It adopts the Distributed Feedback Bragg Grating (DFB) type fiber laser technology and has independent intellectual property to achieve stable linear polarization, single longitudinal mode and ultra-narrow linewidth single-frequency laser output. The unique Relative Intensity Noise (RIN) suppression technique guarantees the low noise operation of the CoSF-D series high power narrow linewidth single frequency fiber laser.

The narrow linewidth single frequency fiber laser of Connet has excellent performance with the output optical spectrum linewidth of kHz level and the ultra-low frequency noise and intensity noise. The basic module of the CoSF-D series narrow linewidth single frequency fiber laser is compact and robust with strong environmental interference capability. The output power can be up to 50mW or more. 

The center wavelength of CoSF-D series 1.0um narrow linewidth single frequency fiber laser basic module can be freely selected in the range of 1010nm to 1120nm. The typical cernter wavelengths are 1018nm, 1030nm, 1053nm, 1064nm and 1083nm, etc.
