最近开发的超声波技术进行评估，通过测量的行为，在水中诱导的飞秒激光脉冲的空化气泡。利用光学击穿过程中的被动声发射来估计空泡的起源位置。进而，基于主动超声脉冲回波信号来限定泡壁的位置。结果表明，开发的超声技术可用于飞秒激光诱导的微泡的定量测量。(C)2008年美国光学学会。
A recently developed ultrasound technique is evaluated by measuring the behavior of a cavitation bubble that is induced in water by a femtosecond laser pulse. The passive acoustic emission during optical breakdown is used to estimate the location of the cavitation bubble's origin. In turn, the position of the bubble wall is defined based on the active ultrasonic pulse-echo signal. The results suggest that the developed ultrasound technique can be used for quantitative measurements of femtosecond laser-induced microbubbles. (C) 2008 Optical Society of America.
