Three-Halves Harmonic Emission From a Laser Filament in a Plasma Channel
نویسندگان
چکیده
A self-trapped laser filament is susceptible to decay-producing radially localized Langmuir waves. A nonlinear interaction of the pump wave with the density oscillation at the Langmuir frequency gives rise to three-halves harmonic emissions. Using a basis-function expansion technique, the emitted power in the backward direction is obtained. It decreases with the increasing size of the filament.

Three-halves harmonic emission from femtosecond laser produced plasmas
Measurements of three-halves harmonic radiation (3v0/2) produced by femtosecond, Ti:sapphire laser pulses (<2310 W/cm) in long density scale length plasmas generated from solid aluminum targets are presented. The 3v0/2 emission yield shows excellent agreement with theories of the two-plasmon decay instability in the predominantly linear regime. © 2002 American Institute of Physics. @DOI: 10.106...
متن کاملEffects of laser-plasma interactions on terahertz radiation from solid targets irradiated by ultrashort intense laser pulses.
Interactions of 100-fs laser pulses with solid targets at intensities of 10(18) W/cm(2) and resultant terahertz (THz) radiation are studied under different laser contrast ratio conditions. THz emission is measured in the specular reflection direction, which appears to decrease as the laser contrast ratio varies from 10(-8) to 10(-6). Correspondingly, the frequency spectra of the reflected light...
متن کاملTime Frequency Analysis of Higher Harmonic Generation in a Three Color Laser Pulse
high harmonic generation is a useful tool for the generation of short, intense attosecond pulses. In order to simulate high harmonic generation, we performed a numerical solution to the time dependent Schrödinger equation. by considering dipole approximation, we predicted generation of a 53 attosecond pulse. In order to see the time and frequency of emission of attosecond pulse, we exploit...
متن کاملPROGRESS IN LASER FUSION 2. D Three-Halves Harmonic Spectra and Self- Focusing in Laser Plasmas
We have recently reported on the spectral characteristics and the generation mechanisms for the harmonic radiation emitted from laserproduced plasmas.' We noted on that occasion that the observed asymmetric splitting of the 3~ , / 2 spectra from UV-laser plasmas (Fig. 16) could not be explained on the basis of a planar plasmaexpansion model. In the preceding article of this review, the theoreti...
متن کاملThree-Halves-Harmonic Radiation from Long-Scale-Length Plasmas Revisited
Introduction Starting with the very early experiments relating to laser fusion, observations have shown acharacteristic spectral emission near the 312 harmonic of the irradiating laser ~ a v e 1 e n ~ t h . l For simplicity we will name this emission "312 self-emission" to distinguish it from similar spectral features that may be induced by a separate probe beam. This spectral signature was imm...
