摘要（英）：

The invention discloses a small repetition-frequency solid state laser device with narrow pulse width and high peak power, which comprises an output mirror, a total reflection mirror, an RTP electro-optic active Q-switching assembly arranged close to the total reflection mirror, a first diode pumping module arranged close to the output mirror and a second diode pumping module located between RTP electro-optic active Q-switching assembly and the first diode pumping module, wherein the first diode pumping module and the second diode pumping module are symmetrically arranged in a staggered manner. The working efficiency of the laser device reaches the optimal state, and a small air-cooled Nd:YAG solid state laser device capable of outputting high-efficiency pumping with the laser energy being85mJ, the pulse width being 3.5ns, the corresponding peak power being 24MW, the repetition frequency being 20hz and the beam dispersion being 2.5mrad within a full temperature range from -40 DEG C to+65 DEG C.
