Abstract

Third-order harmonic generation in carbon nanotubes was investigated using ultrashort pulses generated by a Cr:Forsterite laser, at a wavelength of 1250 nm. An unusual nonperturbative behavior of the third-harmonic yield was found for relatively low input laser fields, of ∼1010 W/cm2. Results showed that in a full quantum-mechanical theory for harmonics generation from a single-walled carbon nanotubes, there was strong nonlinearity of the laser interaction with carbon nanotubes.
