1064nm High Power Short Pulse Fiber Laser for LiDAR (VFLS-1064)

脉冲激光器厚1064

Connet 1064nm high power short pulse fiber laser for LiDAR is a fiber laser source with high peak power and high pulse energy. Using the MOPA configuration and the optimized design of the multi-stage amplification, the laser can achieve the high peak power with the ns level pulse width. This laser is the ideal source for LiDAR applications like 3D scanning, telemetry and range finding.

The VENUS series 1064nm high power short pulse fiber laser for LiDAR employs the module package with compact and rugged design. It has wide operating temperature range with low power consumption. In addition, the pulse output also can be achieved by external TTL trigger signal, which is very suitable for system integration.

Notes:
1. If using the laser for a long time, please place it in a good heat-dissipation environment.
2. Keep the output end face clean.3. Before adjusting the repetition rate from high to low, please set the main output power to zero and then reset the output power according to the actual parameters. The reason is that adjusting the repetition rate from high to low with the same output power and pulse width will cause the single pulse energy sudden increasing. This will easily damage and the output end face and the laser. There is no such influence while adjusting the repetition rate from low to high.
4. The maximum output average power is 5W@7ns/200KHz. When the repetition rate is reduced, the main average output power needs to be reduced to ensure that the pulse peak power is less than 7KW.
5. When the repetition rate is 200KHz and the pulse width is 3~7ns, the main output average power can be up to 5W.
