Abstract
THE first indication of the effects of laser-induced acoustic transients on a macromolecular system has been obtained by exposing monodisperse solutions of tobacco mosaic virus (TMV) to positive acoustic pressure transients with amplitudes of 10 atmospheres or more and lasting 10−7 s. The acoustic transients were produced by the absorption of a 50 ns, 1 J pulse of ruby laser light in an optically dense solution of Prussian blue dye with an optical attenuation coefficient of 1,000 cm−1 for the 6943 Å ruby laser radiation. The laser power density necessary to break the TMV particles was found to depend on the surface boundary conditions of the irradiated medium.
