ダイアモンドのレーザーによる電子励起確率の解析的理論構築とモデルによる数値計算を行い、偏光の楕円率依存性を調べた。その結果、基本的に楕円・円偏光は直線偏光に比べて大幅

Laser excitation in silicon from femto- to pico-second time scales is studied. We assume the three-temperature model which describes the dynamics of the distinct quasi-temperatures for electrons, holes, and lattice. Numerical results for damage thres

Effect of laser wavelength on the carrier-phonon dynamics and damage threshold of silicon is studied numerically. Laser excitation dynamics in silicon is studied using Three-Temperature Model (3TM). We consider the evolution of electron, hole, and la

Laser excitation in Silicon is studied using a new Three-Temperature model. The thresholds for partial melting and electron emission show good agreement with experimental results. Comparison with two-temperature model is also done.

Electron excitation in dielectrics is studied for an elliptically polarized laser field. As the first step, we develop an analytical formula for electron excitation rate under elliptically polarized laser as the extension of our previous work [T.Otob

We study the interaction of intense, sub-cycle, and few-cycle laser pulses with xenon clusters for the generation of mono-energetic electron bunches. For this purpose, we used three dimensional, relativistic, molecular dynamics simulations. In this w
