| 摘 要： | 用Q-YAG泵浦的Rh·6G染料激光在一块45°切割的β-BaB2O4(BBO)晶体中倍频,产生294.8—282.5nm范围的连续调谐输出,其能量为8mJ(在285nm处)。用这个倍频光与泵浦染料后剩余基波(1064nm)在另一块45°切割的BBO中和频,已获得230.8—223.2nm范围的连续调谐输出,其能量为120μJ,相应的峰值功率为12kW。还简述了获得高功率和频输出的关键技术。

| Abstract: | Continuously tunable second harmonic generation of 294.8-282.5 nm was obtained by Q-switched YAG laser pumped Rh·6G dye laser in a 45°cut β-BaB2O4 (BBO) crystal. The output energy of the harmonic wave is about 8mJ around 285 nm. The continuously tunable output over the range of 230.8-223.2 nm was also obtained by the sum frequency mixing between the residual pump fundamental wave (1064nm) and the second harmonic wave of Rh 6G dye laser in an other 45°cut BBO crystal. The sum frequency output energy is about 120 μJ around 226 nm, the corresponding peak power is 12 kW. The key techniques of the sura frequency generation were indicated. |
