Introduction

KY-CTM-xx narrow linewidth tunable single-frequency laser module is used for the Coherent LIDAR, using an unique the semiconductor external cavity structure. The typical output bandwidth is less than 20KHz linewidth and narrow linewidth FM laser module, with ultra-low RIN noise and excellent Frequency modulation performance, is now widely used in vehicle-mounted lidar and optical fiber sensing detection system. This devise complies with Telcordia GR-468 standard and has passed the long-term reliability test.
