2660 A holographic interferometry of laser produced plasmas from tilted disk targets

PDF Version Also Available for Download.

Description

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, ... continued below

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.
