Abstract
A method and apparatus for improving the functionality, quality, and usefulness of a beam of coherent energy used in laser shock processing by utilizing an apodizer within the oscillator or amplifier of a laser. The apodizer used may be a phase plate, a serrated aperture, a birefringent beam shaper, an absorbent graded aperture, a reflective graded aperture, or a combination thereof. A method and apparatus for reducing or preventing damage to an oscillator and an amplifier utilizes an apodizer.
