In this study, we investigate the conversion of femtosecond laser energy deposition from plasma into a shockwave in ambient air. The experiments are carried out using a 380fs pulsed laser at 1.03μm, with laser intensities below the filamentation threshold. The measurements of this dynamic phenomenon are carried out with the help of a time-resolved transmission microscope, and the pressure and temperature space-time evolution are evaluated using a theoretical model. In our conditions we generate shockwaves with initial pressure loading in the range of GPa and maximum propagation velocity in the order of a few km/s.
