Resumen:
We present a theoretical study of atomic ionization due to an XUV pulse in the presence of an infrared laser. Within the strong field approximation and considering the periodicity and symmetry of the transition matrix we show that the photoelectron spectrum can be described from the  contribution during only one (or half) infrared cycle. These symmetry and periodicity properties impress selection rules which destructively cancel  certain sideband orders favoring others. In particular, we analyze the  photoionization of Argon in four geometrical arrangements of the  polarization vector and the photoelectron momentum direction.
