Connet CoSF-D 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 narrow linewidth single frequency fiber laser.

Connet CoSF-D narrow linewidth single frequency fiber laser has excellent performance with the output optical spectrum linewidth of kHz level, the ultra-low frequency noise and intensity noise and the output optical signal noise ratio (OSNR) to be greater than 50dB.

CoSF-D-HP1 high power narrow linewidth single frequency fiber laser internally adopts MOPA design, based on CoSF-D basic module, integrates low noise fiber amplifier and high power double-clad Er/Yb co-doped fiber amplifier to achieve the output power up to 2W. For higher output power, please refer to the technical specifications of CoSF-D-ER-B-HP2/HP3.
