Vv. Apollonov et al., LOW-THRESHOLD GENERATION OF HARMONICS AND SHORT-WAVELENGTH X-RAY-RADIATION IN LASER-PLASMA .1. ONE-PEAK GENERATION, Kvantovaa elektronika, 20(2), 1993, pp. 180-184
A laser plasma source of short-wavelength X-ray radiation is investiga
ted in the case. when parametric instabilities are excited in the sour
ce at low (up to 10 GW/cm) intensities of heating radiation. The pheno
mena observed are qualitatively interpreted.
