Laser ablation scheme can cover pretty wide range of intensity regime as a heat source at its laser focus spot from 103 W/cm2 to 1014 W/cm2. These intensities cover the ones expected at the divertor (MFE) and the first walls (IFE) in a reactor. For example expected values are of 10 to 100 MW/m2 at MFE divertor and 109 W/cm2 or higher at IFE first walls. The ablation may include plasma, gas, liquid, or solid: all possible phases mixed at an extreme condition where temperature may exceed 1 eV with corresponding densities. The areas of these mixed phases at extreme conditions (MPEC) have not been systematically studied. The inside of the solid wall becomes so called “Warm Dense Matter” where the details of the states should still be clarified.In our experimental setting up, the ablated plumes can be aligned orthogonally and can cross each other. The collision processes include Coulomb, elastic, molecular, and cluster collisions at the cross point. The characteristics of this experimental platform are introduced and attractive application is indicated.
