CoSF-D-YB-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 single-frequency laser output with single longitudinal mode, linear polarization, and narrow linewidth. CoSF-D has 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 resistance to environmental interference, and an output power of more than 100mW. CoSF-D-YB-M is based on Yetterbium-doped fiber with narrow linewidth (<20kHz) and low phase noise, low relative intensity noise (RIN). The standard wavelength is 1064nm, 1053nm, 1083nm, and the optional wavelength range is 1010-1120nm. Other wavelengths can be customized according to requirements.
