摘要:

利用定量阴影法,对100 fs激光脉冲在水中产生的光等离子体细丝引起的折射率变化和瞬态吸收进行了时空表征。在非线性焦点附近的等离子体通道的形成和演变进行了观察与23 fs的时间分辨率。

英文摘要:

By means of a quantitative shadowgraphic method, we performed a space-time characterization of the refractive index variation and transient absorption induced by a light-plasma filament generated by a 100 fs laser pulse in water. The formation and evolution of the plasma channel in the proximity of the nonlinear focus were observed with a 23 fs time resolution.
