Abstract In this paper we extend Drinfeld's current realization of quantum affine algebrasU q(ĝ) and of the Yangians in several directions: we construct current operators for non-simple roots of g, define a new braid group action in terms of the current operators, and describe the universalR-matrix for the corresponding “Drinfeld” comultiplication in the forms of an infinite product and of certain integrals over current operators.
