摘　　要：利用非线性光学晶体实现激光频率转换是拓展激光波长的有效手段之一,非线性光学晶体也成为全固态激光系统中的核心器件。硼酸盐由于其丰富的结构多样性和优异的光学性能,已成为开发可用于紫外激光输出的非线性光学晶体的重要体系。K_(3)B_(6)O_(10)Br晶体具有短的紫外截止边(182 nm)、较大的非线性光学系数(d_(22)为0.83 pm/V)、适中的双折射率(0.046@1064 nm),在激光二倍频、三倍频激光输出领域具有潜在应用。本文简要介绍了K_(3)B_(6)O_(10)Br晶体生长及基本性能,对晶体倍频与和频实现可见/紫外激光及光参量啁啾脉冲放大方面的研究进展进行了总结,并对K_(3)B_(6)O_(10)Br晶体未来发展及应用前景进行了简要分析。Using nonlinear optical crystals for laser frequency conversion is a key method for extending laser wavelengths.These crystals,particularly borates,are crucial in all solid-state laser systems,especially for ultraviolet laser output,due to their diverse structures and superior optical properties.The K_(3)B_(6)O_(10)Br crystal,notable for its short ultraviolet cutoff edge(182 nm),significant nonlinear optical coefficient(d_(22) of 0.83 pm/V),and moderate birefringence index(0.046@1064 nm),shows promise in second and third harmonic laser output.This article provides an overview of the growth and fundamental characteristics of the K_(3)B_(6)O_(10)Br crystal.Recent advancements in visible/ultraviolet lasers and optical parametric chirped pulse amplification,achieved through crystal frequency doubling and sum frequency techniques,are summarized.Additionally,the potential future developments and applications of the K_(3)B_(6)O_(10)Br crystal are explored in this study.
