AMRL-001 series is a high frequency nanosecond all solid state laser. These lasers have high peak power, repetition rate over KHz, and pulse width of about 10ns.

Optical design with end pump + acoustooptic Q-switch. Full air cooling design can meet the complex working conditions at wide temperature. Structural stability and reliability, after a long period of customer validation, can achieve 7 × 24 hours of trouble-free operation.

Typical applications are the matching light sources for atmospheric particulate matter lidar. Used for real-time monitoring of atmospheric environment changes. Backscattered light is produced by the interaction of a pulsed laser with particulate matter in the atmosphere. The scattered signal is received by the telescope system and passed through the photoelectric detection system and the signal acquisition system. The spatial distribution of extinction coefficient and depolarization coefficient of atmospheric particulates is then inverted by computer. This enables the detection of atmospheric quality.

a. The output index and shape of 1064nm and 532nm lasers are the same, and they are two lasers of the same model.
b. This laser is convenient for customers. Except for the four laser modules (laser head module, LD pump source module, Q-switch module and circuit control module), it cannot be changed. The layout of other parts of the laser can be adjusted according to customer requirements.
c. The laser cooling fan is adaptive. The power consumption of low-speed operation at room temperature is about 90W, and that of high-speed operation at high temperature is about 200W.
d. Under high temperature, the laser can work normally, but the output energy will be reduced.
