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 high power 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 and the ultra-low frequency noise and intensity noise. The module of the CoSF-D high power narrow linewidth single frequency fiber laser is compact and robust with strong environmental interference capability. It is based on MOPA configuration, integrates CoSF-D seed laser and low noise Polarization amplifier to achieves high power output, The output power can be up to 2W.

The 1.5um CoSF-D narrow linewidth single frequency fiber laser module has two types of products based on different optical configuration. Each type of product has its own unique characteristics, suitable for different applications.

CoSF-D-ER-M:based on Er-doped fiber, ultra-narrow linewidth(<1KHz)and low phase noise.

CoSF-D-EY-M: based on Er-Yb co-doped fiber, narrow linewidth(<15KHz) and low RIN.

The standard wavelength of1.5um CoSF-D narrow linewidth single frequency fiber laser is 1550.12nm .The center wavelength can be chosen freely in the 1530-1570nm range, such as the standard wavelengths of ITU.
