ARPA Semiannual Technical Report, Materials Science

Abstract

This paper has been accepted for publication in the February 1974 issue of the IEEE Journal of Quantum Electronics. It shows the need for further experimental data on induced electric breakdown as a function of wavelength and pulse duration. Consequently a reliable, high power, mode-locked Nd-Yag laser system is being assembled to provide single diffraction limited picosecond pulses, with frequency doubling to green and ultraviolet wave lengths. Details of progress are reported below. Quantitative work on gas breakdown by 10.6 micrometers radiation from a Carbon Dioxide is also reported.
