1.0um Single Frequency Fiber Laser Basic Module
Product Description:
Connet Laser CoSF-1 is a low noise single frequency fiber laser module designed based on Connet'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 particular ultra narrow filter and polarization controlling technology to realize PM, Single Longitudinal Mode ultra-narrow linewidth output.
The CoSF-1 series of 1.0um SF fiber laser basic module features 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 operate in the different kinds of environment and achieve Single Longitudinal Mode output without mode-hopping even under bad condition such as the temperature changes, vibration, shocking etc.
The CoSF-1 series of 1.0um SF fiber laser basic module with mW range output power and higher output power can be customized. The center wavelength can be chosen freely in the 1000-1200nm range such as 1018nm, 1030nm, 1053nm, 1083nm, 1178nm etc.
