CoSF-D-Tm-B-LP 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-LP is a low 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 rangess from 20mW to 100mW. The center wavelength is selectable in the 1900-2100nm 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
