  In a recent work [Mod. Phys. Lett A13, p-1265 (1998)] we expounded a
non-local Quantum Electrodynamics (QED) which predicted a linear two-photon
absorption by an atom placed in a laser field of appropriate intensity and
frequency. In this paper we extend our earlier work to show that the theory
allows for linear 2n-photon absorption by gaseous matter where, under suitable
conditions, n may literally run upto thousands. The consequences of this
extension of the theory are outlined and predictions are made which may be
verified in laboratories.
