Abstract	This article presents a theoretical analysis of laser plume formation in terms of Knudsen layer when a femtosecond laser pulse was irradiated on a thin gold foil in terms of gas dynamics equations. The laser spot was assumed to be noncircular laser spot radius, giving an ellipsoidal form of expansion. The profile of the plume will be discussed depending on the laser fluence and beam waist. Analytical solution of this expansion will be presented for the density of vapor plume. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/30268
