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 1.0um SF fiber laser basic module of the CoSF-1 series 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 be normally operated in different kinds of environments and meanwhile, achieve Single Longitudinal Mode output without mode-hopping even under the bad conditions such as the temperature changes, vibration and shocking, etc.

 

The 1.0um SF fiber laser basic module of the CoSF-1 series is normally with mW range output power and the higher output power can be customized. The center wavelength can be chosen freely in the 1000-1200nm range such as 1018nm, 1030nm, 1053nm, 1083nm and 1178nm, etc.
