Abstract

The invention belongs to the field of laser technology, and discloses a system for measuring the volume of cavitation gas induced by ultrashort pulse laser. The system includes a laser pulse device, a convex lens, a detection device and a photographing device. The detection device is filled with transparent liquid. The convex lens is used to focus the emitted pulsed laser in the transparent liquid in the detection device. The photographing device is used to photograph the cavitation process. , the detection device includes a liquid inlet, a liquid storage chamber and a measurement chamber, the liquid inlet is connected to the liquid storage chamber, when the transparent liquid enters the liquid storage chamber from the liquid inlet and fills the liquid storage chamber and the measurement chamber, the liquid inlet is closed, There is a capillary in the rubber stopper of the opening on the measurement chamber. When the pulse laser is focused in the transparent liquid, the transparent liquid will undergo cavitation and generate air bubbles, which will cause the liquid level in the capillary to rise. By reading the rise of the liquid level in the capillary The volume of gas produced by cavitation is obtained highly. Through the invention, the rapid measurement of the cavitation gas volume is realized.

Description

technical field [0001] The invention belongs to the field of laser technology, and more specifically relates to a system for measuring the volume of cavitation gas induced by ultrashort pulse laser. Background technique [0002] Over time, highly focused ultrashort-pulse lasers have become more widely used in cellular biophysics and biotechnology. The latest research results show that it has been possible to use ultrashort pulse lasers to sample and subsequently biophysically characterize cellular structures. However, despite the continuous development of pulsed laser microbeam technology, the knowledge of the physical mechanisms has been poorly studied, and the knowledge of these physical mechanisms is crucial and will provide a framework to drive further research and development of pulsed laser microbeam technology. . [0003] The experimental research on the interaction mechanism between ultrashort pulse laser and liquid matter mainly focuses on two aspects: one is the ...
