利用时间分辨成像和散射技术，我们直接和间接地监测了八个数量级以上的飞秒激光脉冲在水中引起的击穿动力学。我们首次解决了皮秒等离子体动力学问题，并观察到激光产生的等离子体膨胀前有20 ps的延迟。我们把这种延迟归因于电子离子的能量传递时间。(C) 2002年美国光学学会。
Using time- resolved imaging and scattering techniques, we directly and indirectly monitor the breakdown dynamics induced in water by femtosecond laser pulses over eight orders of magnitude in time. We resolve, for the first time, the picosecond plasma dynamics and observe a 20 ps delay before the laser- produced plasma expands. We attribute this delay to the electron- ion energy transfer time.
