CoLID-Mini 1550nm short pulse fiber laser for LiDAR of Connet is a fiber laser source delivering high peak power and high pulse energy output based on safe wavelength for the human eyes. The optimized design with special configuration can achieve high peak power and ns-level pulse width laser output. It is an ideal light source for LiDAR, telemetry and range finding.
CoLID-Mini 1550nm short pulse fiber laser for LiDAR has a compact structure in small size (70x70x25mm) with wide operating temperature range, low delay jitter and power consumption. The pulse output can be achieved by external TTL trigger signal, which is very suitable for system integration.
