CoSF-D-ER-M Single Frequency Fiber Laser Module

Connet CoSF-D is a low-noise Single Frequency Fiber Laser based on Distributed Feedback Bragg Grating (DFB) technology. It has independent intellectual property rights and achieves a stable singlefrequency laser output with single longitudinal mode, linear polarization, and narrow linewidth. CoSF-D has very low phase and
frequency noise and low relative intensity noise (RIN). Connet uses unique packaging technology to ensure low-noise DFB single frequency fiber lasers with excellent wavelength stability. 

Connet uses extra-cavity technology to significantly suppress the relative intensity noise (RIN) of the DFB single frequency fiber laser, ensuring that the resonant cavity of the single frequency fiber laser is not disturbed. Please refer to CoSF-D-RS series products. 

CoSF-D narrow linewidth single frequency fiber laser module has a small size, a sturdy package, strong resistanceto environmental interference, output power is up to100mW. CoSF-D-ER-M is based on erbium-doped fiber with ultra-narrow inewidth (<1kHz) and low phase noise and frequency noise. The standard wavelength is 1550.12nm, and the optional wavelength range is 1530-1570nm, such as the  standard wavelength under the ITU framework. Other wavelengths can be  customized according to requirements.
