我们通过使用紧密聚焦的100-fs激光脉冲在水中产生最小的破坏性击穿，并展示了这种技术在眼睛显微手术中的潜在应用。利用时间分辨成像和压电式压力检测，我们测量了在击穿过程中产生的压力波的传播幅度和速度。与长脉冲击穿相比，这里的击穿阈值低得多，击穿的能量阈值为0.2微焦耳，冲击区直径较小(1微焦耳脉冲为11微米)，能量沉积一致。
We produce minimally disruptive breakdown in water by using tightly focused 100-fs laser pulses and demonstrate the potential use of this technique in microsurgery of the eye. Using time-resolved imaging and piezoelectric pressure detection, we measure the magnitude and speed of propagation of the pressure wave produced in the breakdown. Compared with breakdown with longer pulses, here there is a much lower energy threshold for breakdown of 0.2microJ , a smaller shock zone diameter (11microm for 1-microJ pulses), and consistent energy deposition.
