Investigation of the relation between the (3/2)omega 0 harmonic emission and filamentation

OSTI ID:6232860
Time-resolved spectra and other features of the (3/2)omega 0 harmonic emission have been investigated together with the filamentation effect in laser-produced plasmas for intensities between 2.5 x 10 to the 13th power and 10 to the 16th power W/sq cm. Temporal fine structures of the (3/2)omega 0 spectra were frequently found to be frequency shifted first to the red and then to the blue. This is consistent with a proposed unstable filamentation model, which described the frequency shift of the (3/2)omega 0 emission as coming mainly from the Doppler shift of the density contours inside the filament during their formation and collapse.
