Paper Abstract

We present a study of the short-timescale fluid dynamic response of water to a fiber-delivered laser pulse of variable energy and spatial profile. The laser pulse was deposited on a stress confinement timescale. The spatial profile was determined by the fiber core radius, r, and the water absorption coefficient, (mu) a. Considering 2D cylindrical symmetry, the combination of fiber radius and absorption coefficient parameters can be characterized as near planar, symmetric, and side-directed. The spatial profile study shows how the stress wave varies as a function of geometry. For example, relatively small absorption coefficients can result in side-propagating shear and tensile fields.
