Pulsed power driven solid liners may be used for a variety of physics experiments involving materials at high stresses. These include shock formation and propagation, material strain-rate effects, material melt, instability growth, and ejecta from sh

The plasma flow switch is a possible fast opening-switch for Z-pinches on inductive-store pulsed-power machines. This paper presents results of two-dimensional, radiation-magnetohydrodynamic models for a well-characterized plasma flow switch operatin

A 10 ps transform limited optical pump pulse two-photon-resonant with the 6 S 1/2 -6 D 32 442 nm transition in Cs vapor generates a coherent state superposition which, after a delay exceeding the pulse width, gives rise to second harmonic emission (w

We demonstrate an effective scheme for passively stabilizing the single shot spectrum of the amplified pulses from a synchronously pumped dye laser system. This scheme is easy to implement and inexpensive. Data from resonant and nonresonant coherent

We propose novel methods for control of light by an electron beam in miniature vacuum tube. Amplitude, phase, frequency, and spatial modulation can be effected, separately or in combination, through manipulation of the electron beam characteristics w

The Laguna foil implosion experiments are part of the Los Alamos foil implosion project, Trailmaster. In the La- guna experiments we are fielding a system that should provide implosion energies of the order of 100 kJ. The Laguna pulse power system co

The Procyon system in the Los Alamos Trailmaster foil implosion project is intended to produce soft x-ray radiation by delivering about 1 MJ of kinetic energy to an imploding plasma Iiner. The final switching stage of this system will be a Plasma Flo

Summary form only given. Energy exchange in a micron-scale zone between a light beam and a free electron beam (EB) can be regulated by control of the EB direction. A 1 V-biased electron deflector may produce light intensity modulation at a rate up to

Summary form only given. The Smith-Purcell free electron laser (SP-FEL) is a potentially compact cw source of tunable mW THz radiation. To achieve this potential, the gain mechanism of the electron beam-electromagnetic wave interaction must be well u
