Modeling of High-Energy Pulsed Laser Interactions with Coupons

Autor: C D Boley, A M Rubenchik

We describe a computational model of laser-materials interactions in the regime accessed by the solid state heat capacity lasers (SSHCLs) built at LLNL. We show that its predictions compare quite favorably with coupon experiments by the 10 kW SSHCL a

Propogation of the 1(mu) High-Power Beam from a Solid-State Heat-Capacity Laser

Autor: J R Moriss, A M Rubenchik, C B Dane, C D Boley

A solid-state laser system, used as a directed energy defensive weapon, possesses many compelling logistical advantages over high-average-power chemical laser systems. As an electrically-powered laser, it uses no chemicals, generates no effluents, an

Computational model of drilling with high radiance pulsed lasers

Autor: J. T. Early, C. D. Boley

Publikováno v: International Congress on Applications of Lasers & Electro-Optics.

A model of drilling by high radiance pulsed lasers is described. The model involves a one-dimensional description of heat transport below the bottom of the hole, hydrodynamic expansion of the vapor and compressed air, and light propagation through th

Interaction of a high-power laser beam with metal sheets

Autor: C. D. Boley, K. P. Cutter, Scott N. Fochs, Paul H. Pax, R. M. Yamamoto, Alexander M. Rubenchik, Mark D. Rotter

Publikováno v: Journal of Applied Physics. 107:043106

Experiments with a high-power laser beam directed onto thin aluminum sheets, with a large spot size, demonstrate that airflow produces a strong enhancement of the interaction. The enhancement is explained in terms of aerodynamic effects. As laser hea

Enhancement of the Neutral-Beam Stopping Cross Section in Fusion Plasmas Due to Multistep Collision Processes

Autor: Ratko K. Janev, C. D. Boley, Douglass E. Post

Publikováno v: Physical Review Letters. 52:534-537

Multistep processes involving excited atomic states are found to produce a substantial increase in the stopping cross section for a neutral hydrogen beam injected into a plasma, and thus to reduce the beam penetration. For typical plasma and beam par

Time-dependent pair distribution in the mean-field approximation

Autor: G. Tenti, C. D. Boley

Publikováno v: Physical Review A. 21:1652-1659

The time-dependent pair-distribution function, which plays a central role in the description of nuclear magnetic relaxation and collision-induced absorption in classical fluids, is evaluated in a mean-field approximation proposed earlier. In this sch

The statistical mechanical resolution of a thermodynamic 'paradox'

Autor: Marlan O. Scully, C. D. Boley

Publikováno v: Journal of Statistical Physics. 24:159-174

We discuss a thermodynamic paradox suggested by Fallows and Greenleaf. Using quantum statistical mechanics, we analyze the problem in detail, showing why no paradox arises.
