  We discuss scaling laws of fusion yields generated by laser-plasma
interactions. The yields are found to scale as a function of the laser power.
The origin of the scaling law in the laser driven fusion yield is derived in
terms of hydrodynamic scaling. We point out that the scaling properties can be
attributed to the laser power dependence of three terms: the reaction rate, the
density of the plasma and the projected range of the plasma particle in the
target medium. The resulting scaling relations have a predictive power that
enables estimating the fusion yield for a nuclear reaction which has not been
investigated by means of the laser accelerated ion beams.
