Abstract: The deformation process of plate material shocked by high-power short pulsed laser is one of the key problems for laser shock forming. In this paper, the finite element software ABAQUS is used to simulate the deformation process. A simple and novel optoelectronic measurement system is applied to measure the deformation process of aluminum sheet. The experiment and simulation results show that the load from the high-power short pulsed laser irradiation can be regard as transient pressure and the dynamic displacement law is damped oscillation.

Abstract: This paper mostly summarizes experimental device of laser-induced plasma and taking pictures of plasma plume. The progress in the experimental study on laser-induced plasma was discussed. The experimental apparatus include the laser、delay device; The system of the plasma radiation gathered and radiation received were reviewed. In addition, photos of plasma plume were discussed; at last, dynamic process of laser-induced plasma plume explosion was discussed.
