Generalized cross sections

and

for the two-photon ionization of He from the metastable

state are calculated for linearly and circularly polarized incident laser light, respectively, in the wavelength range 3725-5100 Å. Significant enhancement of cross sections occurs through real

and

p intermediate states. The ratio

/

shows a minima at the wavelengths close to 3743 and 4450 Å.
