LD-PD's narrow linewidth single-frequency laser 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.The module has a built-in signal generator and supports real-time online pre-distortion correction.
LD-PD's narrow linewidth single-frequency laser has its own patents, high structural stability, mature technology and it is suitable for mass production. This devise complies with Telcordia GR-468 standard and has passed the long-term reliability test.
