Radiochromic film is used extensively in many medical, industrial, and scientific applications. In particular, the film is used in analysis of proton generation and in high intensity laser-plasma experiments where very high dose levels can be obtaine

Laser plasma interactions with high intensity laser pulses can produce high magnetic fields in the 10's of MG range. One technique for generating high magnetic fields in under dense plasmas is via the Inverse Faraday Effect (IFE) which has been shown

Toxic heavy metals can be a significant risk to human health. Lead poisoning has been a recognized health hazard for more than 2000 years. Exposure can occur through drinking water, food, air, soil, and dust from old paint containing lead. Laser-indu

High intensity laser plasma interactions are often affected by the preplasma created by the inherent prepulse of the system due to leakage laser light (typically millijoules over nanoseconds) prior to the arrival of the main high energy laser pulse (

We report on the experimental and simulated characterization of proton acceleration from double-pulse irradiation of um-scale foil targets with varying preplasma conditions. Temporally separated pulses of less than a picosecond in duration have been

A diode-pumped, passively Q-switched Yb:CaF2 laser with Cr:YAG saturable absorber has been developed and characterized. A maximum average output power of 737 mW at a repetition rate of 1060 Hz was obtained with slope efficiency of 20%. The output pul

Cavity ring-down spectroscopy has been used to obtain the spectra of transient (O2)2 at 577 and 629 nm, at room temperature and pressures ranging from about 0.25 to 10.0 atm. A selection of these spectra are displayed showing the overlapping monomer

A simple effusion cell evaporation source for thin film deposition and molecular-beam epitaxy is described. The source consists of a crucible with a thermocouple temperature sensor heated by a resistive crucible heater. Radiation heat transfer from t

We report the fabrication of photovoltaic devices by the anodization of microcrystalline silicon films on single-crystal silicon substrates. The porosity of the films was varied from 20% to 60% by changing the anodization conditions. The influence of

This paper describes a confocal scanning beam MACROscope/Microscope which can image specimens up to 7 × 7 cm in size using reflected light, photoluminescence and optical beam induced current. The MACROscope provides a 10 μm spot size at various wav
