Abstract

Said invention is used for producing powder materials, including colloid solutions with the aid of laser engineering and condensed state processes, in particular for producing different powders and suspensions used for medicine, pharmacology, the agriculture industry and other sectors. The inventive method for producing powder suspensions consists in evaporating a substance by a giant laser pulse whose specific energy ionising an evaporable substance is greater than 109 W/cm2 and whose duration is equal to or greater than 10-8 sec. The evaporable substance is placed on a focal plane with respect to a laser radiation focal point. Vapours are condensed in an optically transparent liquid. The evaporable substance is chaotically displaceable along a discrete path. Said method increases the process efficiency and reduces the coagulation of dispersed powders.
