Integral harmonic intensities in the radiation scattered from nanosecond 10.6-..mu..m laser-target interaction have been studied as a function of laser energy and target orientation. Measurements suggest a power-law dependence of scattered harmonic intensity with increasing laser intensity, I/sub n/..omega..0proportionalI/sup n//sub omega0/, up to approx.1 x 10/sup 14/ W/cm/sup 2/ incident with evidence of saturation above this level. The scattered harmonic light at 7..omega../sub 0/ was found to be fairly isotropic in front of the target.
