Abstract

Diffractive optical elements to modify laser beam spatial intensity distributions are described. The elements have been applied to free-space Gaussian to flat-top beam conversion and customization of the modes of a laser resonator. The single pass free space elements demonstrate a high efficiency but result in to much high frequency noise on the beam. The intra-cavity elements significantly altered the TEM₀₀ profile but practical limitations with the positioning of the element within the cavity prevented operation in the design mode.
