Techniques are provided for formatting laser pulse spatial shape and for
effectively and efficiently delivering the laser energy to a work surface
in the laser shock process. An appropriately formatted pulse helps to
eliminate breakdown and generate uniform shocks. The invention uses a high
power laser technology capable of meeting the laser requirements for a
high throughput process, that is, a laser which can treat many square
centimeters of surface area per second. The shock process has a broad
range of applications, especially in the aerospace industry, where
treating parts to reduce or eliminate corrosion failure is very important.
The invention may be used for treating metal components to improve
strength and corrosion resistance. The invention has a broad range of
applications for parts that are currently shot peened and/or require
peening by means other than shot peening. Major applications for the
invention are in the automotive and aerospace industries for components
such as turbine blades, compressor components, gears, etc.
