摘　　要：结合板条激光器和薄片激光器的特点设计了一种表层增益板条激光器结构。采用基于慢轴像中继的抽运耦合系统实现抽运光在板条宽度方向的均匀分布。利用表层增益板条激光器实现了稳定的准连续激光输出,在抽运频率300Hz、抽运脉宽200μs,抽运单脉冲能量354mJ条件下,实现了单脉冲能量121.3mJ的1064nm激光输出,对应的光光转换效率和斜率效率分别为34.3%和45%。We designed a novel surface gain slab laser combining the characteristics of slab lasers and disk lasers. A pumping system based on image relaying along the slow axis was used to obtain the uniform distribution of pumping light in the slab width direction. We achieved stable quasi continuous laser output with the surface gain slab laser. The maximum output energy of 1064 nm laser pulse is 121.3 mJ when the pumping repetition rate is 300 Hz, the pulse width is 200 gs, and the pumping energy of a single pulse is 354 mJ. The corresponding optical-to-optical efficiency and the slope efficiency are 34.3% and 45%, respectively.
