Abstract

We present a new theoretical approach for collisional absorption of laser energy in dense plasmas which accommodates arbitrary frequencies and high intensities of the laser field by establishing a connection between laser absorption by inverse bremsstrahlung and the stopping power for ions. This relation is then applied to include strong correlations beyond the mean field approach. The results show excellent agreement with molecular dynamics simulations up to very high coupling strength.

Collisional absorption of dense plasmas in strong laser fields: Quantum statistical results and simulation

Journal Article Hilse, Paul ; Schlanges, Manfred ; Bornath, Thomas ; ... - Physical Review. E, Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics

Collisional absorption of dense fully ionized plasmas in strong laser fields is investigated using quantum statistical methods as well as molecular dynamics simulations. For high-frequency fields, quantum statistical expressions for the electrical current density and the electron-ion collision frequency are presented. Strong correlations are taken into account and their influence on the absorption rate is discussed. The expressions are valid for arbitrary field strength assuming the nonrelativistic case. In addition, molecular dynamics simulations were performed to calculate the heating of dense plasmas in laser fields. Comparisons with the analytic results for different plasma parameters are given. There are considered themore »« less

Collisional absorption of laser light in under-dense plasma: The role of Coulomb logarithm

Journal Article Kundu, M. - Physics of Plasmas

In this work, we re-examine collisional absorption of 800 nm wavelength laser pulses in under-dense plasma. For a given temperature and density of the plasma, most of the conventional models of the electron-ion collision frequency ν{sub ei}, with a Coulomb logarithm independent of the electron-ponderomotive velocity, show that ν{sub ei} and the corresponding fractional laser absorption α remain almost constant (or decrease slowly) up to a value I{sub c} of the peak intensity I{sub 0} of the laser pulse, and then ν{sub ei} and α decrease as ≈I{sub 0}{sup −3/2} when I{sub 0} is increased beyond I{sub c}. On the contrary,more »« less

Examination of classical coupling of laser light to thin, dense plasma layers

Journal Article Osborn, R K - IEEE Trans. Plasma Sci., v. PS-3, no. 3, pp. 116-121

Classical absorption, i.e., inverse bremsstrahlung, is examined in the context of two different models of the radiation field and the plasma. One model is developed by approximations starting from Maxwell's equations plus a hydrodynamic description of the plasma. The other is based upon a model of photon transport. It is shown that the laser-plasma coupling implied by these models appears (at least qualitatively) to be quite different. According to the Maxwell-hydrodynamic model, thin but dense plasma layers are strongly reflecting whereas the photon transport model seems to imply that they are strongly absorptive. This discrepancy is not a paradox butmore »« less

The effect of external magnetic field on the bremsstrahlung nonlinear absorption mechanism in the interaction of high intensity short laser pulse with collisional underdense plasma

Journal Article Sedaghat, M. ; Ettehadi-Abari, M. ; Shokri, B., E-mail: b-shokri@sbu.ac.ir ; ... - Physics of Plasmas

Laser absorption in the interaction between ultra-intense femtosecond laser and solid density plasma is studied theoretically here in the intensity range Iλ{sup 2}≃10{sup 14}−10{sup 16}Wcm{sup −2}μm{sup 2}. The collisional effect is found to be significant when the incident laser intensity is less than 10{sup 16}Wcm{sup −2}μm{sup 2}. In the current work, the propagation of a high frequency electromagnetic wave, for underdense collisional plasma in the presence of an external magnetic field is investigated. It is shown that, by considering the effect of the ponderomotive force in collisional magnetized plasmas, the increase of laser pulse intensity leads to steepening of themore »« less

Laser light scattering and absorption in dense, spherically symmetric plasmas

Thesis/Dissertation Erkkila, John Howe

A computational study of the interaction of a focused laser beam with a dense, spherically symmetric plasma is undertaken. The plasma is treated using linearized fluid equations for the electrons with the ions assumed immobile; the electromagnetic field is determined from steady state solutions to Maxwell's equations in spherical coordinates. Energy dissipation in the plasma occurs as a result of Inverse bremsstrahlung collisions and resonance absorption. The scattered field distribution and the spatial variation of the fields and energy deposition within the plasma are found for various laser-plasma configurations and the applicability of the theory as a function of plasmamore »« less
