摘　　要：为了获得结构紧凑的瓦级实用化高峰值全固态355nm紫外激光器,采用简单紧凑的平平直腔结构,使用声光Q开关进行调制,通过LD端面抽运Nd:YAG激光晶体,在重复频率1kHz～50kHz的情况下,产生平均功率1.03W～6.1W的1064nm红外光;采用LBO晶体进行2倍频和3倍频,在重复频率10kHz时得到紫外的最高输出功率1.08W,峰值12kW;在重复频率5kHz时得到紫外的最高峰值功率为17kW。结果表明,该方案满足了实际的应用需求。In order to get a compact watt-level high peak power UV laser, a compact plane-plane linear cavity, LD end pumped acoustic-optic Q-switched configuration was used, from which 1.03W -6. 1W 1064nm IR laser at 1kHz -50kHz repetition rate was obtained. With a LBO crystal employed to generate the second and third harmonic wave, the maximum output power of 1.08W UV at lOkHz repetition rate was achieved with peak power up to 12kW. The maximum peak power of UV laser was 17kW at 5kHz. The resules show that the practical application was satisfied in many fields.
