This article studies the relativistic self-focusing of an intense laser beam in underdense plasma. Due to relativistic self-focusing of the laser beam, a transverse intensity gradient is created, and this can generate a plasma wave at the pump wave frequency. The mechanism of the plasma wave, second-harmonic generation, and the parameters which govern the second-harmonic yield, have been studied in detail. For a typical laser with wavelength (λ=1.053 μm), intensity (1018 W cm-2) and a plasma having density (ωp/ω0=0.25), the second-harmonic intensity was found to be around (1014 W cm-2). © 2004 American Institute of Physics.
