Abstract

See full text

A laser hole drilling system includes a laser source that generates a laser beam along an optical axis; a spherical lens along the optical axis downstream of the laser source; and a control system in communication with the spherical lens and the laser source, the control system operable to locate the spherical lens with respect to the laser source to produce a light distribution in polar coordinates of a real portion of the Fourier Transform to generate an asymmetric teardrop shaped energy distribution at a focal plane.
