Abstract. A model experiment on mass transfer process in an aqueous solution of glycerol under the action of low-power laser radiation is carried out at weak absorption of the radiation by the medium. The concentration of glycerol solution providing the most pronounced mass transfer effect is determined as 9:1. The presented dependences of the radiation power transmitted through the area of exposure, and the temperature in the area center, on duration of the radiation action, confirm the effect of mass transfer.
Keywords: mass transfer, low-power laser radiation, glycerol solution
