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
