In this paper we provide an extension theorem for fractional powers of some pseudo-differential operators P(D). These extensions yields realization of the fractional powers of some pseudo-differential operators in the spirit of Caffarelli and Silvestre \citeCSilv. In particular every fractional power of a local pseudo-differential operator can be realized locally. We also give some properties of the relativistic Schrödinger operator \Dsm.
