Estimate of pressure produced during explosive boiling of a liquid film on a substrate heated by laser pulses

Experimental data of Lang and Leiderer [New J. Phys. 8, 14 (2006)] on the movement of a thin liquid film due to its explosive boiling on a substrate heated by a nanosecond laser pulse are analysed. It is shown that the maximum value of the pressure pulse produced in this case without any singularities may be much lower than the estimate obtained by these authors and is in good agreement with the assumption that the explosion is initiated in the vicinity of the spinodal.
