Measurement and Control of the Properties of Gases Produced by Ablation of Delrin (Polyformaldehyde) with a CO2 Laser

Abstract

The primary objective of this research is to enable control of the properties of gases that are produced by ablation of solid Delrin with a pulsed C02 laser. Target gas properties are: (1) a specific energy content greater than 100 MJ/Kg, (2) a specific impulse range from 200 to 800 seconds, and (3) an overall conversion efficiency of laser energy to jet kinetic energy of at least 50%.
