Method and device for stand-off laser drilling and cutting
Abstract
A device for perforating material and a method of stand-off drilling using a laser. In its basic form a free-running laser beam creates a melt on the target and then a Q-switched short duration pulse is used to remove the material through the creation of a laser detonation wave. The advantage is a drilling/cutting method capable of working a target at lengthy stand-off distance. The device may employ 2 lasers or a single one operated in a free-running/Q-switched dual mode.
