Phys. Rev. A 54, R1769–R1772 (1996)Generation and control of high harmonics by laser interaction with transmission electrons in a thin crystal
We propose a mechanism of generating very high harmonics at moderate laser intensities by transmission of electrons in a thin crystal. Results of nonperturbative Floquet-Bloch calculations show the possibility of controlling the height and range of high-harmonic spectra through the mechanism of interband resonances at suitable energies of the incident electrons and/or intensity of the laser field. © 1996 The American Physical Society URL:
