摘要：

Two-photon absorption measurements on InSb, obtained with a single mode hybrid CO2 laser, have been analysed, taking into account the fact that the laser is Gaussian in space and the effect of free-hole absorption on the temporal profile. The dependence on wavelength of the two-photon coefficient at room temperature (K2=8 cm(MW)-1 for 10.6 mu m and K2=14 cm(MW)-1 for 9.6 mu m pumping) agrees well with a new calculation including the effect of non-parabolic bands. A similar measurement on Hg0.78Cd0.22Te (K2=14.0 cm(MW)-1 for 10.6 mu m pumping) is consistent with this.
