CoSF-D-YB-B-MP Narrow Linewidth Single Frequency Fiber Laser

Description:

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 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-YB-B-MP is based on Yetterbium-doped fiber with narrow linewidth (<20kHz) and low phase noise, low relative intensity noise (RIN). Output power is from 200mW to 10W. The standard wavelength is 1064nm, 1053nm, 1083nm, and the optional wavelength range is 1010-1120nm. Other wavelengths can be customized according to requirements.
