摘要

本文用压电共振激光量热法测量了三硼酸锂晶体在1070 nm和532 nm的偏振单模激光辐射作用下，在50 ~ 300和5 ~ 50 W的功率范围内的低光吸收和散射系数。结果表明，当辐射沿晶体轴a传播时，这些系数在指定的功率范围内保持恒定，并且不依赖于激光辐射偏振方向。将测量的光学散射系数与积分球法得到的结果进行了比较。

Measurements of small optical absorption and scattering coefficients of high-power polarised laser radiation in lithium triborate crystals

We present the results of measurements of low optical absorption and scattering coefficients in lithium triborate crystals using the method of piezoelectric resonance laser calorimetry under the action of polarised single-mode laser radiation at wavelengths of 1070 and 532 nm in the power ranges of 50 – 300 and 5 – 50 W, respectively. It is shown that when radiation propagates along the crystal axis a, these coefficients remain constant in the specified power ranges and do not depend on the direction of laser radiation polarisation. The measured optical scattering coefficients are compared with the results obtained by the method of integrating spheres.
