[en] The ''Flora'' installation is developed to carry out a combined plasma heating by power laser radiation (PLR) and relativistic electrone beam (REB). The installation consists of a 20-channel power neodymium laser with the energy of 1kJ (pulse duration equals 2ns) and of the ''Plasma focus'' installation with the following parameters: condenser battery energy equals 52kJ, work voltage is 27kW, neutron yield equals 2-4x10⁹ neutron/pulse. The description of the main parts of the ''Flora'' installation and laser radiation characteristics are given. The processes of PLR and REB combined interaction with the current plasma and solid target are theoretically studied. It is shown that at PLR and REB combined interaction on a thermonuclear target with the ''Plasma focus'' battery energy of 4x10⁴J in case of using solid targets of a special construction the neutron yield up to 10¹² neutron/pulse is possible
