Photographic studies of laser‐induced pressure impulses in liquids
TLDR
In this article, shadow photography techniques have been used to study various effects produced in transparent liquids by the focused beam from a Q-spoiled ruby laser, including the intense spherical acoustic transients generated in water and other pure liquids when dielectric breakdown occurs.Abstract:
Shadow photography techniques have been used to study various effects produced in transparent liquids by the focused beam from a Q‐spoiled ruby laser. The intense spherical acoustic transients generated in water and other pure liquids when dielectric breakdown occurs have been examined. In solutions of benzanthracene in benzene, in which other workers have detected two‐photon absorption, a linear region is strongly affected by the laser beam and cylindrical acoustic disturbances have been observed.read more

Laser-induced breakdown in aqueous media
TL;DR: In this paper, the effects of laser-induced breakdown in aqueous media were investigated and applications of laser induced breakdown in liquids in liquids were discussed. But none of these applications were considered in this paper.

Laser‐generated stress waves
TL;DR: In this paper, a method of generating stress waves with a laser was demonstrated using a transparent material to impede the expansion of the vaporized absorber, whose magnitude was 34 kbar and whose width at half-maximum was equal to the width of the laser pulse.

Werner Lauterborn,Alfred Vogel +1 more
TL;DR: In this paper, the authors reviewed the first findings after the invention of the laser to the present state of knowledge, including dielectric breakdown with plasma and bubble formation, the breakdown shock wave, bubble dynamics with expansion and collapse, and bubble collapse shock wave or waves.

High‐speed holography of laser‐induced breakdown in liquids
W. Lauterborn,K. J. Ebeling +1 more
TL;DR: In this paper, the phenomenon of ruby laser-induced breakdown in liquids is investigated by high-speed holography, and the advantage of using holographic instead of ordinary photography lies in the possibility to easily suppress the bright white light emitted during the breakdown process.

Laser induced underwater sparks
TL;DR: In this paper, a 30MW Q-switched ruby laser was focused into water, and the resulting spark revealed a blackbody-like spectrum with a temperature of 15 000°K.

TL;DR: In this article, a technique for observing high pressure shock waves generated in water by Q-switched lasers is described, using the laser as an illuminating source for a shadowgraph system and as a tool for generating the shocks.

TL;DR: Stimulated Brillouin scattering of intense laser light with build-up of coherent hypersonic waves in liquids was studied in this article, where the authors showed that it is possible to construct a coherent coherent HWA in liquids.
