| 摘 要： | 受到晶体尺寸以及非线性光学性能的影响,目前可供选择的非线性晶体非常有限。DKDP晶体作为传统大尺寸光电材料,在光参量啁啾脉冲放大(OPCPA)装置中得到了应用。高氘化的DKDP晶体有更好的光学性能,然而生长出高氘化DKDP晶体对生长环境等有更加严格的要求。本文通过改良的原料合成罐以及生长槽,采用点籽晶快速生长法成功生长出高氘DKDP晶体。按照Ⅰ类(θ=37.23°, φ=45°)切割方式制备样品,并对其氘含量、透过率、光学均匀性以及晶体激光损伤阈值进行测试。实验结果表明,晶体的平均氘含量达到98.49%,在可见-近红外波段下具有较宽的透过波段和较高的透过性能。R-on-1的测试结果显示,在3 ns、527 nm条件下,DKDP晶体的激光损伤阈值达到了19.92 J/cm2。晶体光学均匀性均方根达到了1.833×10-9,表明晶体具有良好的光学均匀性。

| Abstract: | Due to the influence of crystal size and nonlinear optical properties, the available nonlinear crystals are very limited. As a traditional large-size photoelectric material, DKDP crystal has been applied in optical parametric chirped pulse amplification (OPCPA) devices. Highly deuterium DKDP crystals have better optical properties, but the growth of highly deuterium DKDP crystals has more stringent requirements on the growth environment. In this paper, highly deuterium DKDP crystals were successfully grown by rapid growth of point seed crystals through an improved raw material synthesis tank and the growth tank. The samples were prepared according to the type I (θ=37.23°, φ=45°) cutting method, and their deuterium content, transmittance, optical homogeneity and laser-induced damage threshold of crystals were tested. The results show that the average deuterium content of the crystal reaches 98.49%, and the crystal has a wide transmission band and high transmission performance in the visible-near infrared band. The test results of R-on-1 show that the laser-induced damage threshold of DKDP crystal reaches 19.92 J/cm2 at 3 ns, 527 nm. The root-mean-square of optical homogeneity of the crystal reaches 1.833×10-9, indicating that the crystal has good optical homogeneity. |
