1 Secondary shock emitted during the collapse and rebound of a laserexcited cavitation bubble / Nguyen Thi Phuong Thao // .- 2020 .- Số 06(43) .- P. 31-34 .- 530
The secondary shock emitted at the collapse and rebound of a laser-induced cavitation bubble was studied directly and visually by the photoelasticity imaging technique. The result shows the image of the pressure wave transmitted into the solid target due to the impact of the secondary shock. From the observation, we recommend that the secondary shock is quite strong and homogeneous, thus can be utilized to provide additional machining effect to the laser ablation process.
2 Direct observation of a laser-excited circular acoustic wave crossing a solid-liquid interface by photoelasticity imagine technique = Quan sát trực tiếp một sóng âm hình cầu sinh ra bởi tia laser đi qua một bề mặt phân cách rắn-lỏng bằng phương pháp quang / Nguyen Thi Phuong Thao // .- 2021 .- Số 02(45) .- P. 35-38 .- 530
This technique provides a clear, whole field image of the phenomena; and is a promising method to study the acoustic phenomena at the interfaces.
