摘要
为提高激光倍频过程的温度适应宽度, 提出了利用非主平面相位匹配方法降低LiB3O5(LBO)晶体中的激光倍频的温度敏感性。研究发现, 利用LBO晶体进行1 064 nm激光倍频过程时, 存在部分不在主平面上的相位匹配方向, 该方向上的倍频温度半宽相对于传统主平面方向上的相位匹配温度半宽更宽。实验中, 利用切割角度(θ=58.4°, φ=27.0°)的LBO晶体进行波长为1 064 nm的激光倍频, 其温度半宽度达76.0 ℃, 约为传统主平面相位匹配倍频温度半宽度的12倍。
Abstract
In order to improve the acceptance temperature bandwidth of laser second harmonic generation, temperature insensitivity of laser second harmonic generation in LiB3O5 (LBO) crystal is proposed by using non-principal plane phase matching method. It is found that when using the LBO crystal for second harmonic generation of 1 064 nm laser, there is a phase matching direction that is not on the principal plane, and the temperature full width at the half maximum (FWHM) in this direction is wider than that in the conventional principal plane direction. In the experiment, the LBO crystal with a cutting angle of (θ=58.4°, φ=27.0°) is used for second harmonic generation of 1 064 nm laser, and the temperature FWHM is 76.0 ℃, which is 12 times the temperature FWHM of traditional principal plane phase matching.
