A method as claimed in claim 5 further comprising firing the laser beam without flowing a fluid curtain over the coated surface upon which the laser beam is firing to form a pattern of overlapping laser beam spots while moving the laser relative to the workpiece. 7. A method as claimed in claim 5 further comprising firing the laser beam while flowing a fluid curtain over the ablative coated surface upon which the laser beam is firing to form a pattern of overlapping laser beam spots while moving the laser relative to the workpiece. 8. A method as claimed in claim 5 wherein the workpiece is moved linearly to produce a row of overlapping circular laser beam spots having generally equally spaced apart linearly aligned center points. 9. A method as claimed in claim 5 wherein the workpiece is moved and the laser beam is fired to produce more than one row of overlapping circular laser beam spots having generally equally spaced apart linearly aligned center points wherein adjacent rows of spots overlap. 10. A method as claimed in claim 5 wherein the explosive ingredient is nitroglycerin or ammonium nitrate. 11. A method as claimed in claim 5 further comprising forming the ablative coated surface by covering a laser shock peening surface on the workpiece with an ablative material containing two or more explosive ingredients wherein each of the explosive ingredients has a different shock sensitivity and firing the laser beam with sufficient power to explode at least some amount of each of the explosive ingredients. 12. A method as claimed in claim 11 wherein the explosive ingredients are selected from the group consisting of nitroglycerin, pentaerythritol tetranitrate, RDX, and ammonium nitrate. 13. A method as claimed in claim 5 wherein the laser shock peened surface is laser shock peened using a set of sequences wherein each sequence comprises coating the ablative coated surface with the coating and then continuously moving the workpiece while continuously firing a stationary laser beam on the surface such that adjacent laser shock peened circular spots are hit in different ones of said sequences in said set. 14. A method as claimed in claim 13 further comprising a plurality of said sequences wherein essentially each spot is hit more than once in different ones of said plurality and only once in any one of said sequences. 15. A method as claimed in claim 14 wherein the laser beam is fired and the workpiece moved so that the center points of adjacent spots in adjacent rows are offset from each other a generally equal amount in a direction along a line on which the center points are linearly aligned. 16. A method of laser shock peening a metallic workpiece, said method comprising the following steps: forming a film covered surface by adhesively covering a laser shock peening surface on the workpiece with a film including at least one explosive ingredient mixed into a plasticizer, continuously firing a laser beam, which repeatably pulses between relatively constant periods, on the film covered laser shock peening surface of the workpiece while providing continuous movement between the laser beam and the metallic workpiece, and firing the laser beam with sufficient power to explode at least some amount of the explosive ingredient with the pulses and forming laser beam spots on the film and forming a region in the workpiece having deep compressive residual stresses imparted by the laser beam pulsing such that the region extends into the workpiece from the laser
