Abstract

Diffractive optical elements (DOEs) are applied to a number of laser beam shaping tasks. These tasks include customization of the modes of a laser resonator, lensless beam propagation and a free-space Gaussian to flattop beam conversion. The inherent design of the DOE to operate in the near-IR wavelengths and to convert a TEM00 beam of diameter of approx. 20 mm to a circular flattop of diameter approx. 15 mm after a distance of 2 m allows it perform these tasks. The efficiency with which this can be performed is approx. 90% for 16 quantization levels.
