Based upon the closed form of the Humbert confluent hypergeometric function Psi1, the properties of Gauss hypergeometric function F21 and the Pochhammer’s symbol, we investigate some transformation and representation formulas associated with Psi1 . Several equations are deduced in the present study. These results can be used in many physical areas, particularly in the description of the donut laser beams.
