Abstract

An intracavity technique with temporal sensitivity to optical losses is used to detect parasitic infrared absorption (PIRA) in Ti:sapphire crystals with high active-center concentrations. By means of comparative analysis, re-emission is established of part of the parasitically absorbed energy back into the laser action channel. A method is proposed for approximate quantitative determination of the relative part of re-emitting PIRA-centers with respect to their total number; for the highly-doped crystal described, it is estimated at about 11%.

Ti:蓝宝石激光器寄生红外吸收的时间腔内检测
利用一种对光学损耗具有时间敏感性的腔内技术,检测了高活性中心浓度钛蓝宝石晶体中的寄生红外吸收(PIRA)。通过对比分析,建立了寄生吸收的部分能量再发射回激光作用通道的理论。提出了一种近似定量测定再发射pira中心相对于其总数的相对部分的方法;对于所描述的高掺杂晶体,估计约为11%。
