We will present experimental results on formation of supersonic radiatively cooled plasma jets with dimensionless parameters (Mach number ˜20, cooling parameter ˜1 and density contrast ρ_j/ρ_a ˜10), similar to those in YSO jets. Two different experimental configurations are used. In the first the produced jets are purely hydrodynamic and are used to study deflection of the jets by the cross-wind. The ``cross wind'' leads to deflection of the jet through formation of internal oblique shocks in the jet and we will discuss the relevance of these observations to the astrophysical systems. In the second configuration the jets have toroidal magnetic field and the plasma beta in these jets is of the order of unity. We will present experimental data on the dynamics of ``magnetic bubble'' surrounding the jet and on the development of m=0,1 instabilities in the jet. Modifications of the experimental configuration allowing addition of the poloidal magnetic field and angular momentum to the jet will be also discussed. The experimental results will be compared with computer simulations performed with laboratory plasma codes and with astrophysical codes.
