It is developed based on our domestically leading high-energy all-solid-state laser technology solution. It employs a multi-configuration high-temperature LD array end-pumping Nd:YAG crystal combined with high-extinction-ratio electro-optic Q-switching technology to achieve typical 1064nm pulsed laser output with a single-pulse energy of 130mJ.
This product breaks through the technical bottleneck in China where high energy output could not be achieved simultaneously with large pulse width. Under the condition of 130mJ energy, the pulse width can stably maintain an output of 12ns. Additionally, a high-magnification laser beam expansion system is adopted to achieve a beam divergence angle of less than 0.16mrad.
The entire device can operate continuously within an ambient temperature range of -45°C to 60°C, meeting typical long-cycle (short-cycle) illumination requirements of 60s (30s) per single cycle with 40s (10s) intervals for 2 (8) cycles.
It can be mounted on airborne or other electro-optical pods to perform ranging and periodic illumination of targets, supporting the overall system in executing laser semi-active guidance missions.
