深紫外激光器在工业和科学研究中有着广泛的应用。对于266 nm紫外激光的产生，1064 nm激光良好的光束质量和KTP晶体灰迹效应的消除是两个关键因素。使用动态稳定的谐振腔设计，1064-nm的激光器，平均功率为52 W，重复频率为16 kHz。测量的表征光束质量的M2因子为1.5。通过消除KTP晶体的灰迹效应，实现了18 W的绿色激光输出，M2因子为1.6。采用BBO晶体四倍频，获得了1.9W的266 nm紫外激光输出.
Deep ultraviolet lasers have various applications in industries and scientific researches. For 266-nm ultraviolet (UV) laser generation, the good beam quality of 1064-nm laser and the elimination of gray-tracking effect of KTP crystal are two key factors. Using a dynamically stable resonator design, 1064-nm laser with an average power of 52 W is realized with repetition rate of 16 kHz. The measured M2 factor characterizing the beam quality is 1.5. By the elimination of gray-tracking effect of KTP crystal, an 18-W green laser is realized with the M2 factor of 1.6. Using a BBO crystal for the fourth harmonic generation, a 1.9-W 266-nm UV laser is achieved.
