“…The use of former clusters in HHG studies has long attracted the attention of researchers. The HHG spectra of carbon nanotubes (CNTs) have been theoretically studied in [10][11][12][13]. It has been suggested that there are many reasons for using the nanotubes to generate highorder harmonics.…”

We analyse the morphology of the laser plasmas produced on surfaces containing various carbon clusters (nanotubes, nanofibres, fullerenes, and nanoparticles). It is shown that the presence of C5–C25 nanoparticles in the laser plasmas coincides with the enhancement of harmonics in the spectral range of 40–80 nm. We suggest that these nanoparticles, rather than larger clusters, play a decisive role in the observed growth of harmonic yield.

“…The generation of high-order harmonics from a single-walled CNT interacting with a bichromatic laser field (fundamental and its second harmonic) has been investigated [26], where the nonlinear motion of electrons in metallic CNTs driven by intense laser fields has been studied and the induced current spectrum has been analyzed. The effect of variation of the intensity of the applied laser fields on electron current density and HHG has been investigated.…”

“…The effect of variation of the intensity of the applied laser fields on electron current density and HHG has been investigated. Numerical calculations have shown that, with the application of the bichromatic laser field, both odd and even harmonics can be generated [26].…”

High-order harmonic generation in carbon-nanotube-containing plasma plumes

High-order harmonic generation (HHG) in carbon-nanotube (CNT)-containing plasma plumes has been demonstrated. Various targets were ablated to produce the plasma plumes containing nanotubes for the HHG in these media. Harmonics up to the 29th order were generated. Odd and even harmonics were generated using a two-color pump. The integrity of CNTs within the plasma plume, indicating nanotubes as the source of high-order harmonics, was confirmed by structural studies of plasma debris.

“…If a nonlinear system is irradiated by an intense laser field, it reradiates the harmonics of the incident field. The generation of optical high harmonics is one example of the many interesting new phenomena that occur when intense ultrashort laser pulses interact with systems such as clusters [3], graphene layers [4] and CNTs [5][6][7][8][9][10][11][12][13][14][15]. Xie and Jiang theoretically studied the magnitude of the third-order nonlinear polarizability of armchair nanotubes [5].…”

The nonlinear optical response of semiconductor single-walled carbon nanotubes excited by a strong laser field in a two-band approximation, applying a nonperturbative method based on the numerical solutions of quantum kinetic equations has been studied. The density matrix equations including the Rabi frequency were derived from the Schrödinger equation, and then the high harmonic generation spectra were calculated by Fourier transforming the induced current density for nanotubes. Numerical results are presented for three different single-walled nanotubes (13, 0), (16, 0) and (19, 0).
