A new concept for the fusion reactor based on powerful Z-pinch combined with femtosecond
laser driver is suggested. The reactor operates with D3He fuel contained inside a 9Be liner, whose
implosion due to Z-pinch discharge makes possible to compress the D3He plasma up to a high
density and hold it in a state of plasma filament during some time τ. When an end face of the
plasma filament is irradiated by a high-intensity femtosecond laser pulse, a shock wave of
detonation appears in the D3He fuel and then runs along the filament. The shock wave additionally
compresses and heats the fuel to temperatures, at which the D3He plasma burning is essentially
enhanced. This allows getting the self-sustaining wave of detonation along the filament. It is shown
that the interaction of the femtosecond laser pulse with the relatively cold initial Be plasma can
trigger the fast ignition of burning wave along the fuel filament.
