Method and device for improving constraint effect of laser high temperature shot blasting

The invention discloses a method and a device for improving a constraint effect of laser high temperature shot blasting. The method is characterized in that surge pressure generated by high voltage pulse gas is utilized for carrying out constraint on the pressure generated by explosion of laser induced plasma, and the method can be used for solving the problem that a restraint layer such as water flow is not suitable for laser high temperature shot blasting under the condition that plasma coagulation is not influenced, overcoming the defect of local cracking or integral fracture generated on high-temperature-resistant glass due to local press, and substantially improving the effectiveness and reliability of the restraint layer for laser high temperature shot blasting. The device comprises a laser, a heating platform, a pneumatic pump, an accumulator, an electromagnetic switch, a computer system and the like. The method and the device provided by the invention have the advantages that the application range is wide, and the constraint effect is good.
