Research of laser pump and energy storage techniques by F N Mastrup( Book )

2 editions published in 1965 in Undetermined and English and held by 2 WorldCat member libraries worldwide

A fast high radiance ablating laser pump of novel design has been constructed and its radiative characteristics have been determined. Performance of the lamp for exciting a ruby crystal of 0.580 in. diameter and 8 in. length has been established. Total stimulated emission energies in the range 10 joules to 30 joules, depending on individual rods, have been verified. Laser energy was emitted in times near 25 micro sec. The stimulated emission pulse consisted of a series of spikes highly regular with respect to their mutual separation and peak power. Maximum measured peak spike power was 2.5 x 1,000,000 watts.

Hydrogen Fluoride Laser Technology Study (CCN)( Book )

1 edition published in 1972 in English and held by 1 WorldCat member library worldwide

In the course of performing the work discussed in this report, the basic feasibility of Rayleigh Scattering, Raman Scattering and Holographic Interferometry as HF/DF laser cavity diagnostic techniques was investigated. A new HF/DF chemical laser system designated CL III was designed, fabricated and underwent preliminary testing to evaluate reactant mixing of parallel, fully developed H2 and F supersonic flows in the lasing cavity and scaling to higher power while maintaining good potential for pressure recovery
Radiation measurements from a pulsed high-pressure nitrogen arc( Book )

1 edition published in 1968 in English and held by 1 WorldCat member library worldwide

The program was an experimental and theoretical determination of the ultraviolet and vacuum ultraviolet emission from pulsed high pressure nitrogen arcs at pressures up to 1000 atm. For this purpose, a pressure vessel was designed and constructed for the containment of gas pressures up to 1000 atm. In addition, an ignition mechanism, which allowed breaking down of 1000 atm nitrogen arc gaps of 1/4 inch and a pulse forming network, which discharged rectangular current pulses of 2 - 10 kiloamperes magnitude and 650 microseconds duration through the 1000 atm nitrogen was designed and constructed. The breakdown apparatus utilized an ignition wire across the gap. High speed pictures of the discharge showed that a luminous plume, with 'hot spots', and not a cylindrical discharge, resulted from the discharge. Photographic spectra showed the 1000 atm nitrogen arc emission was primarily a continuum in the spectral region 1950 - 3000 A; no line emission was observed in the spectral region 1450 - 3000 A. Although local thermodynamic equilibrium was expected, the radiation pulse shapes at several wavelengths in the region 1600 - 4000 A showed erratic behavior and a quasi-stationary state was obtained at all studied wavelengths, only near the end of the rectangular discharge (500 - 700 microseconds after ignition). Quantitative measurements of the spectral radiance of a 1000 atm nitrogen arc with 4 kiloamperes current in the region 1700 - 4000 A at this quasi-stationary state, showed that the emission was a continuum, peaking at 2500 - 3000 A, and becoming extremely weak at wavelengths smaller than 1900 A.

ELECTRON ATTACHMENT OF SEF6( )

1 edition published in 1961 in English and held by 0 WorldCat member libraries worldwide

During recent years, formation of negative ions as received considerable attention because of its intimate relationship to atmospheric physics and to some plasmas of low and moderate temperatures. Experimental results recently obtained in a laboratory st on the formation of negative ions of SeF6 by collisions with electr ns having energies in the range from 0.1 eV - 1.5 EV are discussed. This analysis deal with attachment through two-body collisions
