| Outline of Final Research Achievements |
The transition from excited states of the dielectric to plasmas is an important issue in the ablation in the solid by the high-power continuous-wave lasers. We proposed the kinetic model to describe the creation and annihilation of the excited states, evaluated the temperature increase in the dielectric by the heat conduction model, and experimentally measured the absorption coefficient of nonlinear optical crystal.
The condition of the amplification of the second harmonics using lithium tantalate as a nonlinear crystal was evaluated by solving the heat conduction equation and the nonlinear wave equation including the absorption based on the model.
