The CoLID series 1550nm short pulse fiber laser for LiDAR of Connet is an eye-safe pulsed laser source with high peak power and high pulse energy. Based on the Master Oscillator Power-Amplifier (MOPA) configuration and the optimized design of multi-stage optical amplification, the laser can reach high peak power and ns pulse width output. It is an ideal fiber laser source for LiDAR, telemetry and range finding.
Connet CoLID series 1550nm short pulse fiber laser for LiDAR adopts the mini disc type module and the rectangular type package with compact structure and small size. The laser has wide operating temperature range with low power consumption. The pulse output also can be achieved by external TTL trigger signal, which is very suitable for system integration.
At present, Connet CoLID series fiber lasers includes the below two subseries: CoLID-I and CoLID-II:
