| Abstract: | Under suitable conditions on laser intensity, focal spot radius and atomic number a radiative jet was launched from a planar
target. This jet was produced using a relatively low energy laser pulse, below 500 J and it presents similarities with astrophysical
protostellar jets. It lasts more than 10 ns, extends over several millimeters, has velocity more than 500 km/s, the Mach number
more than 10 and the density above 1018 cm−3. The mechanism of jet formation was inferred from the dimensional analysis and hydrodynamic two-dimensional simulations.
It is related to the radiative cooling while the magnetic fields play a minor role.
