1. A method of avoiding back-strike damage that may happen during a water jet guided laser machining processes comprising:providing a first body to be machined via a water jet guided laser, said first body having a plurality of walls defining an exterior surface and an interior surface, said interior surface of the first body defining a hollow interior volume;
connecting the first body to a volume vibrator via an inlet hole located on the first body to create a mechanical energy within said hollow interior volume, said volume vibrator pumping in and pumping out a media into the hollow interior volume of said first body to create the mechanical energy via the oscillation of the media;
providing the first body with an outlet hole may be plugged via a plug to control to ensure the vibrating media is located a laser beam breakthrough location by eliminating a path of least resistance;
filling the hollow interior volume of the first body with the media;
pumping in and out the media to the hollow interior volume to cause a vibration of the media within the hollow interior volume;
machining the exterior surface of the first body via providing the water jet guided laser which is a laminar flow to create the laser beam breakthrough location in a first portion of said plurality of walls such that when the water jet guided laser creates an opening through the first portion of said plurality of walls the laminar flow of said water jet guided laser meets the vibrating media within said hollow interior volume the mechanical energy disrupts the laminar flow of the water jet guided laser to scatter the laminar flow of the water jet guided laser such that the laser does not impinge on and start creating a deformity on a second portion of said plurality of walls defining the interior volume opposite of the first portion;
wherein the vibration of the media and plugging of the outlet hole if required ensures that the hollow interior volume is free of any dead corners such that all locations within the hollow interior volume are affected by the mechanical energy.
