Development of New Laser-Protective Dyes. Phase 1.

Abstract

The overall purpose of this Phase I research effort is to develop dyes that will be used to provide eve protection against lasers that emit light energy in the 650 nm to 1050 nm range. One of the major problems with available dyes is that they can be thermally and photochemically unstable. These drawbacks seriously limit the utility of present laser protective dyes. The objective of the Steadfast Phase I research program was to demonstrate the feasibility of stabilizing certain laser-protective dyes using Steadfast chemical and processing technology. In the Phase I work, five different dyes were identified and/or synthesized and studied. Results showed that thermal stability was improved in four of the five dyes studied. This was accomplished by (1) chemical dye structure modification and (2) system additive methodology. In another set of experiments, excellent photochemical stability was found in one of the dye structures studied. Overall, background information is provided indicating that thermal stability of laser-protective dyes can be improved by applying Steadfast techniques.
