.... Images are taken from the back of the sample at various time delays with respect to the beginning of the ablation process, allowing the transient hole area to be measured. For low fluences, the hole opening process is delayed long after the laser pulse and there is significant scatter in the data due...

...S. Rameche Candane; C. Balaji; S. P. Venkateshan A quasi-one-dimensional ablation analysis for a sharp-nosed, reusable, re-entry vehicle that could possibly be used in an unmanned space program, has been carried out by using an in-house code. The code is based on the boundary immobilization...

...Michael Epstein This paper presents a one-dimensional steady-state model of heat and water vapor transport just beneath an ablating concrete surface. In the model an evaporation front separates a dry porous region through which water vapor flows to the ablation front from a semi-infinite region...

... the thermodynamic critical point, the liquid undergoes a phase explosion that turns the melt into a mixture of liquid and vapor. This article describes heat transfer and phase change phenomena during nanosecond pulsed laser ablation of a metal, with an emphasis on phase explosion and non-equilibrium phase change...

...). The non-Fourier effect would not be observed using the continuum approach either. In this section, various phenomena accompanying phase change in an argon target illuminated with a laser pulse of 0.7 J/m 2 are investigated in detail. The threshold fluence for ablation is also studied. Towards...

...S. S. Chu; C. P. Grigoropoulos Pulsed laser deposition (PLD) of thin films has become a viable technique for a wide range of applications over the last few decades. As kinetic energy of the ablated plume is an important parameter in determining the quality of the film; consequently there is great...

...V. Petrushevsky; S. Cohen A one-dimensional, nonlinear inverse heat conduction problem with surface ablation is considered. In-depth temperature measurements are used to restore the heat flux and the surface recession history. The presented method elaborates a whole domain, parameter estimation...

... melting and ablation of material, also result in large localized thermal stresses within the narrow heat-affected zone, which can lead to microcracks, significant decrease in bending strength, and even catastrophic failure. In order to assess the where, when, and what stresses occur during laser drilling...
