Simultaneous Spectrally and Spatially Resolved Measurements of3ω02Emission from Laser-Produced Plasmas

Abstract
Measurements of three-halves harmonic emission from laser-produced plasmas are presented. The emission from molybdenum targets irradiated with 1.06-μm laser light is simultaneously spectrally and spatially resolved. The data show a clear spatial separation between the blue-shifted and red-shifted components of the three-halves emission. Spectral structure suggests that ion mode coupling is involved in the scattering process.
