A simple, compact, double-pass pumped Nd:YVO4 thin disk laser is demonstrated. Its continuous-wave performance with different Nd doping concentrations and thicknesses is investigated experimentally. The maximum output power of 17.7 W is achieved by employing a 0.5 at.% doped sample, corresponding to an optical-to-optical efficiency of 46% with respect to the absorbed pump power. In addition, a numerical analysis and an experimental study of the temperature distribution, and thermal lens effect of the Nd:YVO4 thin disk, are presented considering the influence of the energy transfer upconversion effect and the temperature dependence of the thermal conductivity tensor. The simulated results are in good agreement with the experimental results.

激光回波强度为点云数据的一种属性信息,是目标对发射激光光束后向散射回波的光功率,可以反映目标物体的表面特性。毛竹表面特征由其生理生长特性决定,通过分析激光回波强度信息,构建不同年龄竹秆的节间与激光回波强度的关系模型,比较不同年龄毛竹拟合激光回波强度与实测激光回波强度的均方根误差,以此判别毛竹的年龄,并验证分析模型精度。结果表明:不同年龄和不同节间毛竹竹秆激光回波强度差异性显著,节间内激光回波强度的
Instead of praises from colleagues, the claim of observation of metallic hydrogen at 495 GPa by Dias and Silvera met much skepticism, and grew into a public debate at the International Conference on High-Pressure Science and Technology, AIRAPT26. We brief
