A simplified Coulomb explosion model is presented for the analysis of the explosion dynamics of hydrogen clusters driven by an ultrashort intense laser pulse. The scaling of the proton kinetic energy with cluster size has been studied in detail based on t
A method for isochromatic determination in three-fringe photoelasticity is presented. It combines the phase-shifting method with cubic polynomial curve-fitting technology to eliminate the errors caused by color repetition. We perform a demonstration of th
