本文对生长大尺寸硼酸铯锂（ＣｓＬｉＢ６Ｏ１０ ，简称ＣＬＢＯ） 单晶的生长工艺进行了探索研究，采用顶部籽晶泡生法生长出尺寸为７０ ×２５ｍｍ 的ＣＬＢＯ透明晶体。测量了晶体的干涉图，计算其折射率变化为Δｎ～１ ．２ ×１０ － ５ ，晶体的光学质量接近于玻璃水平（ ～１０ － ６） 。测量ＣＬＢＯ单晶的结构及其光学特性。用１５ｍｍ ×１０ｍｍ ×７ｍｍ 的ＣＬＢＯ 样品，在锁模Ｎｄ∶ＹＡＧ 激光器上做倍频实验，获得了波长为５３２ｎｍ 的倍频光，其转换效率高达６０ ％ 以上。
In this paper, the growth of CsLiB6O10 (CLBO) single crystal grown on a large scale has been studied. The CLBO transparent crystal with the size of 70 × 25mm has been grown by the top seed bubble generation method. The interference pattern of the crystal was measured and the change of the refractive index was calculated as Δn ~ 1. 2 × 10 - 5, the optical quality of the crystal is close to the glass level (~ 10 - 6). The structure and optical properties of the CLBO single crystal were measured. With the CLBO sample of 15mm × 10mm × 7mm, frequency doubling experiments on mode - locked Nd:YAG laser show that the doubling frequency is 532nm and the conversion efficiency is up to 60%.
