Abstract :
The ITM is used to describe the MI of atoms of gases under the bicolor femtosecond laser irradiation. The obtained formulas are applied for the qualitative explanation of recent experiments on the generation of THz radiation from an optical breakdown in a focus spot of a femtosecond laser in a gas.
