摘　　要：基于CFD模拟仿真技术,优化了激光腔体散热鳍片的微通道结构和数量,采用折叠腔LD双端泵浦抽运方式,使用高速电光Q开关进行调制、LBO晶体进行倍频和和频。在重复频率为15kHz时得到最大输出功率为12.34 W和最窄脉宽为12ns的稳定紫外脉冲输出,基频光的光-光转换效率约为41%。Based on CFD simulation technology, the structure and number of micro-channels of heat-sink of laser cavity is optimized. A folded resonance cavity is composed of two laser diode side-pumped Nd： YAG modules, an electro-optic Q-switch, two LBO crystals separately as a second harmonic generator and a third harmonic generator. A maximum output power at 355 nm of 12.34 W is obtained at repetition rate of 15 kHz. The corresponding pulse width is 12 ns. And the optical to optical conversion efficiency of the fundamental laser is about 41%.
