Abstract

The invention discloses a method for driving a nonmetal flyer with laser, which includes the step: enabling the laser generated by a laser device to enter an ablation layer on optical glass, enabling materials on the ablation layer to instantly evaporate, gasify and ionize so that high-temperature and high-pressure plasmas are generated, and under restraint of the optical glass, enabling high-pressure shock waves generated by the plasmas to act on the other face of the ablation layer and be positioned on a nonmetal film in front of an incident area, so that the residual non-metal film is sheared and driven at a high speed, and the high-speed flyer is formed. The method and an implementation device can make up the defect that a current laser-driven flyer can only emit metallic grits so that non-metal grits can be emitted, and can also be applied to the field of high-pressure physics, space science, material micro-forming technology, rapid initiation of explosives and the like. When a space debris environment is simulated in a laser-driven flyer manner in the space science, the debris environment can be efficiently simulated by alternately using various flyer materials.

Description

technical field

[0001] The invention relates to the technical field of plasma-driven acceleration, in particular to a method for driving a non-metallic flyer by a laser. Background technique

[0002] Since the inception of lasers, extensive research has been carried out on the interaction of lasers with materials. In the early 1990s, humans first proposed the concept of laser drive, that is, using laser to propel objects to fly at high speed. Subsequently, laser-driven flyer technology was gradually discovered.

[0003] Laser-driven flyer is a dynamic high-voltage loading technology, and its physical basis is the gasification and ablation of the target caused by strong laser irradiation. In the 1980s, D.L.Paisley achieved the first low-energy laser pulse to drive aluminum and copper, and was the pioneer of laser-driven flyers; in 1990, W.M.Trott broke through the limitations of previous atmospheric transmission and used optical fiber transmission to drive aluminum films; i...
