Using double exposure holographic interferometry, an investigation has been made of the Nd laser produced plasmas surrounding disk targets irradiated at different angles of incidence. Measurements have produced a detailed description of the plasma profile necessary for realistic simulations of resonance absorption. A 2660A 15 psec probe pulse is produced by frequency quadrupling a fraction of the main Nd laser pulse from the Janus laser. F/1 and f/10 lenses were utilized to irradiate the targets with intensities ranging from 10/sup 13/ w/cm/sup 2/ to 10/sup 16/ w/cm/sup 2/. Measurements have produced the shape of the electron density profile near critical, the direction of the plasma blowoff, and revealed transverse rippling of the isodensity surfaces.
