Optical probing of the temperature transients during pulsed-laser induced boiling of liquids
Abstract
The thermodynamics of the rapid boiling of a liquid on a solid surface heated by an excimer laser pulse is studied experimentally. The dynamics of bubble nucleation, growth, and collapse is detected by probing the optical specular reflectance. The transient temperature field is measured by monitoring the reflectance of a thin film with calibrated optical properties. The metastability behavior of the liquid and the criterion for the liquid-vapor phase transition in nanosecond time scale are obtained for the pressure from 1 atmosphere to 3.3 MPa. © 1996 American Institute of Physics.
