SIMTRUM provides the 1 μm single-frequency ultra-narrow linewidth fiber lasers based on high gain short-cavity technology to achieve laser output with narrow linewidth (better than 10 kHz), high power stability (RMS <0.5% @8 hours), and excellent beam quality (M2 <1.05).
 
With a slow tuning range of 0.8 nm and a fast tuning range of >8 GHz, the laser adopts a polarization-preserving fiber design to achieve a stable single-polarization output, ensuring long-term single-frequency and mode-hopping-free stable operation, and has been widely used in the fields of laser communication, LIDAR, laser ranging, and laser sensing.
