A method and a device for increasing a laser induced shock wave pressure. According to the method, plasmas () are generated by impinging an aluminium foil () using lasers; a high-voltage pulse electrode () discharges to the plasmas () to induce and form a photoelectric combined energy field and then high-temperature plasmas () having the characteristics of an ultra-high density and an ultra-high speed expansion are induced and generated; a surface to be processed is impacted by the high-temperature plasmas () in a restrained state; the laser induced shock wave pressure is increased substantially; the surface of a high-strength material is reinforced, and the strength, hardness, abrasion resistance and anti-fatigue performances of the high-strength material are improved. The device comprises a laser, the electrode (), a high-voltage power supply (), a discharging medium (), a moving platform, etc.
