Laser Beam Target Interaction. Volume II. Laser Effects at 10.6 Microns
Abstract
This report is the second of two volumes on the subject of Laser Beam Target Interaction. Volume I considered both the performance and design of a pulsed chemical laser and the laser effects measurements made with that laser. This volume describes both impulse and thermal coupling measurements made at 10. 6 microns wavelength. The laser used was the Boeing double-pulse Marx Bank laser which can emit two 15 joule pulses with any desired pulse separation (from simultaneous to several seconds). Spectroscopic measurements were used to determine some of the basic properties of laser-supported absorption waves. In addition, however, a limited amount of data was gathered in order to determine the threshold intensity for igniting laser-supported absorption (LSA) waves from magnesium. The main goal of the work reported here was to determine impulse coupling and thermal coupling at high intensities. One of the most important results was to determine the spatial dependence of absorbed energy on a target at high laser intensities.
