CoSF-D-Tm-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.
CoSF-D-Tm-B-MP is a medium power single frequency fiber laser based on Thulium-doped fiber with narrow linewidth (<15kHz) and low phase noise, low relative intensity noise (RIN). Output power ranges from 200mW to 10W. The center wavelength can be selected in the 1900nm to 2100nm range. Other wavelengths can be customized according to requirements.
Features:
● Narrow linewidth <15kHz
● Low relative intensity noise (RIN)
● Stable single frequency, single polarization output
● No mode-hopping
● High reliability
Applications:
● Frequency conversion
● Coherent LiDAR
● Laser spectroscopy
● Gas absorption measurement
● Other scientific research
