Abstract

Since the mid 1960s laser fusion problems are the subject of active study in many countries of the world. To achieve self-sustaining fusion reaction, the DT fuel densities of 100 - 200 g/cm³, specific areal densities of 0.3 - 0.5 g/cm², and ion temperatures of 3 - 5 keV are required. It is a rather difficult task to realize these extremely high parameters using high-power laser radiation. For the past thirty years performance of various types of targets has been studied including direct-drive and indirect drive targets with single- and multilayered shell pellets. Numerous factors which take effect in implosion physics were investigated. A rich calculational and theoretical material has been obtained. There have been developed and built high-power laser facilities at several laboratories worldwide, some of them are operational. Their parameters are given. All the facilities employ the same optical scheme namely the scheme of direct amplification, and this is one of the reasons for a relatively low efficiency. The main physical results obtained in laser ICF are given. (truncated)
