Abstract

Atomic lines of some chemical elements like sodium and magnesium were investigated for laser breakdown of water with the ultrasound field. The effect of magnification of these atomic lines resolution for salt water in ultrasound field was obtained. It is shown that the method of registration of acoustic emission from a breakdown zone allows to investigate thresholds and dynamics of laser breakdown which will be in accord with high-speed optical methods. The study revealed important practical applications of acoustic emission for breakdown and diagnostics of cavitation in opaque environments.

超声场激光击穿引起的原子线强度放大
研究了超声场激光击穿水中钠、镁等化学元素的原子谱线。得到了这些原子线的放大倍数对超声场中海水分辨率的影响。结果表明,对击穿区声发射的配准方法可以研究激光击穿的阈值和动力学,这与高速光学方法是一致的。该研究揭示了声发射在不透明环境中击穿和空化诊断方面的重要实际应用。
