Nf. Bunkin et Av. Lobeyev, INFLUENCE OF DISSOLVED-GAS ON OPTICAL-BREAKDOWN AND SMALL-ANGLE SCATTERING OF LIGHT IN LIQUIDS, Physics letters. A, 229(5), 1997, pp. 327-333
It is demonstrated that the small-angle laser beam scattering pattern
in liquid depends greatly on the dissolved gas content: the intensity
of the scattering steeply drops after degassing doubly distilled water
. It was experimentally found that the parameters or small-angle scatt
ering of light correlate strongly with those of optical breakdown in l
iquid. Namely, the fractal dimension and the gyration radius of scatte
rers in aqueous KCl solutions behave similar to the optical breakdown
probability in those liquids versus salt concentration, while the opti
cal breakdown cannot be induced after degassing. The effect might be a
ssociated with the presence of stable gas microbubbles in liquid. (C)
