The generation of high-order harmonics from a single walled carbon nanotube interacting with a bichromatic laser field is investigated. We study the nonlinear motion of pi electrons in metallic carbon nanotubes ((9,0) zigzag and (10,10) armchair) driven by intense laser fields and the induced current spectrum has been analyzed. The effect of variation intensity of the applied laser fields on electron current density and high-order harmonic generation is investigated. Numerical calculations show that with application of the bichromatic laser field both odd and even harmonics are generated.
