摘　　要：分别在有氧气氛(空气)和还原气氛(氢气/氩气混合气)下生长了YAl_3(BO_3)_4(YAB)晶体,并研究了不同生长条件下生长的YAB晶体的透过和266 nm激光的输出性能。结果表明,还原气氛下生长的YAB晶体能够消除266 nm附近的吸收,但是晶体的266 nm输出性能并未得到提高。分析推测了可能的原因,并对下一步工作提出可行性的建议。The fourth hormanic generation and transmittance spectra of YAB crystals, which were grown in air or non -oxygen atmosphere （HE/Ar） , had been studies. The results indicate that the absorption of YAB crystal grown in non -oxygen atmosphere at 266 nm is eliminated, but the conversion efficiency of YAB crystal grown in non-oxygen atmosphere from 532 nm to 266 nm is lower than that of YAB crystal grown in air. The reasons had been speculated and the suggestions had been given in the paper.
