Miniature high-power all-solid-state Nd∶YAG slab laser with liquid metal heat conduction

In order to fulfill the requirements of small opto-electronic systems for miniature high power lasers, a heat conduction manner based on liquid metal was designed, which improved the heat transfer efficiency, and a high energy laser with a small volume was made. Using compound slab active materials integrated resonator and laser amplification technology, when the supply current was 80 A and the pulse frequency was 5 Hz, a 160 mJ pulse laser at 1.064 nm was obtained, with a pulse width of 6 ns and a divergence angle of 3 mrad.
