Abstract

Three methods are described for a high-speed diagnos-tics of compression dynamics of shell targets being spherically laser-heated on the installation "Kal'mar". The first method is based on the direct investigation of the space-time evolution of the critiical-density region for lid-laser emission (Ne 1021 Iicm-)) by ears of the streak photography of plasma image in the second-harmonic light. The second method involves investigation of time evolution of the second-harmonic spectral distribution by means of a spectrograph coupled with a streak camera. The use of a special laser pulse with two time-distributed intensity maxima for the irradiation of shell targets, and the analysis of the obtained X-ray pin-hole pictures constitute the basis of the third method.
