A method for setting up a transparent confinement media nozzle for flowing the confinement media during laser shock peening of a work piece includes the following steps: Step A) flowing a confinement media and setting a flow rate of the confinement media through a confinement media flow nozzle; Step B) positioning the nozzle to flow the confinement media through the nozzle and onto the correlation surface; and Step C) measuring a confinement media layer thickness on the correlation surface using an ultrasonic transducer attached to a side of the test piece opposite that of the correlation surface. The ultrasonic transducer is attached to a side of the test piece opposite that of the correlation surface. One embodiment of the invention employs the work piece as the test piece and the correlation surface is a first laser shock peening surface on a first side of the work piece. Further embodiments includes Step D) comparing the measured and recorded confinement media layer thickness from Step C) against a predetermined value or range of values for confinement media layer thickness and Step E) determining whether to reset the confinement media flow rate and/or nozzle position or proceeding with the laser shock peening of the work piece with the confinement media flow rate and nozzle position set in

[ What is claimed is:] [24.]24. A method for controlling the thickness of a flowing confinement media during a laser shock peening method of production work pieces, said process comprising the following steps:performing a setup procedure for setting up a transparent confinement media nozzle for flowing the confinement media on a first laser shock peening surface on a first side of a work piece during the laser shock peening of the work piece, said setup procedure comprising the following steps performed for a plurality of center points of a corresponding plurality of spots to be laser shock peened on the first laser shock peening surface:A) flowing a confinement media and setting a flow rate of the confinement media through a confinement media flow nozzle,B) positioning the nozzle to flow the confinement media through the nozzle and onto the first laser shock peening surface for each of the points using a first controllable manipulator holding the work piece to set work piece attitude and work piece position and a second controllable manipulator holding the nozzle to set nozzle attitude and nozzle position, andC) adjusting the nozzle attitude and the nozzle position with the second manipulator while measuring a plurality of confinement media layer thicknesses corresponding to each of the points to be laser shock peened using an ultrasonic transducer attached to a second side of the work piece opposite that of the first side.
