Relativistic laser harmonic generation from plasmas with density ripple
A high intensity laser obliquely incident on an underdense plasma with density ripple produces resonant second and third-harmonic radiation in the reflected component. The highest efficiency of harmonic generation occurs when the pump laser is incident at critical angle and the angle between ripple wave vector q and the surface normal has a specific value / — /m, at which phase-matching conditi...
متن کاملResonant third harmonic generation of KrF laser in Ar gas.
Investigations of emission of harmonics from argon gas jet irradiated by 700 fs, 5 mJ pulses from a KrF laser are presented. Harmonics conversion was optimized by varying the experimental geometry and the nozzle size. For the collection of the harmonic radiation silicon and solar-blind diamond semiconductor detectors equipped with charge preamplifiers were applied. The possibility of using a si...
متن کاملPhase Matched Third Harmonic Generation of a Gaussian Laser Pulse in High-Density Quantum Plasma
Third harmonic generation due to linearly polarized Gaussian laser pulse propagating through quantum plasma immersed in transverse wiggler magnetic field is studied using the quantum hydrodynamic (QHD)model. The effects associated with the Fermi pressure, the Bohm potential and the electron spin have been taken into account.Wiggler magnetic field plays both a dynamic role in producing the harmo...
متن کاملSecond-Harmonic Generation of Laser Radiation in a Plasma with a Density Ripple
High-power laser radiation with frequency u>i and wave vector ktz propagating through a plasma at an angle to a density ripple (0, fco) produces current and density perturbation at (u>i ,ki + ko). The density perturbation couples with the oscillatory velocity at (wi, fci) to produce nonlinear current at [2^'1.(2 A-1 + k0)] driving second-harmonic electromagnetic radiation. For a specific value ...
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...
