Factory wholesale Fiber Optic Current Sensor - 1.5um CoSF-R Narrow Linewidth Single Frequency Fiber Laser Basic Module – Connet Laser Detail:

Product Description:

Connet Laser CoSF-1 is a low noise single frequency fiber laser module designed based on Connet Laser’s proprietary technology, a patent pending “Optimized Ring Cavity” designed to eliminate the standing wave Spatial Hole Burning (SHB) phenomenon which appears easily in short linear cavity. It comes with the particular ultra-narrow filter and the polarization controlling technology to realize PM, single longitudinal mode and ultra-narrow linewidth output.

The CoSF-1 series 1.5um SF fiber laser basic module features the ultra-narrow linewidth in the kHz range, extremely low RIN and intensity noise and excellent SMSR more than 50dB. In addition, CoSF-1 takes unique high-intensity package to ensure that it can normally be operated in different kinds of environments and achieve single longitudinal mode output without mode-hopping even under the bad conditions such as the temperature changes, vibration and shocking, etc.

The CoSF-1 series 1.5um single frequency fiber laser basic module is normally with mW range output power and the higher output power can be customized. The center wavelength can be chosen freely in the range of 1535-1605nm, such as the standard wavelengths of ITU.
Features:
• Ultra narrow Lorentzian linewidth <1kHz 
• Stable single frequency & single polarization operation
• No mode-hopping, No out-bursting noise

• Low phase and intensity noise
• Flexible design, various wavelengths optional

• PM output, high PER
• Smart module, robust package

Applications:

• Fiber Optic Sensor
• LiDAR
• Acoustic sensing and pipeline monitoring
• Laser spectroscopy
• Coherent Communications

• Gas absorption measurement
• Metrology

• RF and microwave photonics
