“…1 Interfacial explosive boiling has been the subject of intense experimental and theoretical studies over the last few decades. [1][2][3][4][5][6][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Historically, such experiments using optical reflectance, 9,10 scattering, 10 transmission, 11 interferometric 12 and beam deflection 13,14 techniques, as well as photoacoustics 14,15 were started on atomically rough surfaces of Cr or Ag thin metallic films immersed in bulk low-boiling organic liquids ͑or water͒ and heated by pulsed nanosecond laser radiation. As a result, submicrosecond bubble nucleation has been observed at very moderate boiling parameters-degree of superheating ⌬T Ϸ 20-100 K ͑Refs.…”

Explosive boiling and lift-off of a thin layer of micron-sized transparent water droplets from an absorbing Si substrate heated by a nanosecond KrF laser were studied using a contact photoacoustic technique. The compressive photoacoustic response increases steeply to an asymptotic value on the order of the water critical pressure starting at a threshold laser fluence of 0.20J∕cm2, where lift-off of the water layer also occurs. Above this threshold, several reproducible discrete multimegahertz components are revealed in Fourier spectra of the acoustic transients, corresponding to nanosecond oscillations of steam bubbles inside the water droplets on the microsecond time scale of the lift-off process. The acoustic pressure buildup, bubble dynamics, and the subsequent lift-off of the thin water layer are interpreted as relaxation stages after near-spinodal explosive boiling of the superheated interfacial water.

“…Grigoropoulos and co-workers [28][29][30][31][32][33] gave a detailed description of the thermodynamic and kinetic behaviors of nucleation, growth, and collapse of the bubbles using optical techniques. Interestingly, studies indicated that the temperature could reach several thousand K and the pressure could go into the order in magnitude of GPa inside the plasma plume generated by PLA in liquids.…”

The effect of ambient gas on the expansion dynamics of the plasma generated by laser ablation of an aluminum target has been investigated using frequency doubled radiation from a Q-switched Nd:YAG laser. The diagnostic tools include fast photography of overall visible plume emission using a 2 ns gated intensified charged coupled device and space and time resolved emission spectroscopy using a 50 cm monochromator/spectrograph and photomultiplier tube. The expansion behavior of the plasma was studied with ambient air pressure ranging from 10 Ϫ6 to 100 Torr. Free expansion, plume splitting and sharpening, hydrodynamic instability, and stagnation of the plume were observed at different pressure levels. Space and time resolved emission spectroscopic studies showed a twin peak distribution for Al and Al ϩ species at farther distances illustrating plume splitting at pressures higher than 100 mTorr. Combining imaging together with time resolved emission diagnostics, a triple structure of the plume was observed. The expansion of the plume front was compared with various expansion models and found to be generally in good agreement.
