Terahertz Radiation from Argon Clusters Irradiated by Intense Femtosecond Laser Pulses
The electromagnetic wave ranging from the millimeter wave to gamma ray is radiated from plasmas produced by irradiating solid and gas targets with high intensity optical pulses. Recently, several theoretical works have pointed out the possibility that laser produced plasmas radiate intense THz wave [1]. The laser produced plasma is one of the promising candidates for an efficient generator of t...
متن کاملTime Domain Spectroscopy of Terahertz Radiation from Argon Clusters Irradiated by Intense Femtosecond Laser Pulses
The electromagnetic wave ranging from the millimeter wave to gamma ray is radiated from plasmas produced by irradiating solid and gas targets with high intensity optical pulses. The THz wave radiation from the plasmas produced by femtosecond laser pulses has been intensively studied by many groups [1-3] these few years since it is one of the promising intense THz radiation sources. Solid THz em...
متن کاملCollimated fast electron emission from long wires irradiated by intense femtosecond laser pulses.
We have experimentally demonstrated that fast electrons emitted from a metallic wire irradiated by a 5 × 10(18) W/cm(2) laser pulse can be collimated along the wire, and that their intensity is significantly enhanced in the axial direction of the wire. As the wire length is increased up to 30 mm from the laser focal spot, the angular divergence of the emitted electrons with energies of hundreds...
متن کاملElectron Confinement and Heating in Laser-irradiated Micro-clusters
It is shown that a two component electron distribution can emerge in a cluster under an intense laser pulse. A bulk of internal electrons adjusts adiabatically to the laser field whereas a smaller electron population at the cluster edge can undergo stochastic heating. Self-consistent equilibrium has been found and collective modes discussed for the confined electrons.
متن کاملFemtosecond non-equilibrium dynamics of clusters irradiated with short intense VUV pulses
The kinetic Boltzmann equation is used to model the non-equilibrium ionization phase that initiates the evolution of atomic clusters irradiated with single pulses of intense vacuum ultraviolet radiation. The duration of the pulses is ≤ 50 fs and their intensity in the focus is ≤ 10 14 W/cm 2. This statistical model includes various processes contributing to the sample dynamics at this particula...
