Thermal Lensing-Free Chalcogenide Windows

Triton Systems, Inc. along with our academic partner have reviewed the commercial and academic literature on chalcogenide glasses that have high transparency in the near infrared.  Based on this, as a team we have identified potential ChG compositional ranges that could meet the Navy's stringent requirements.  We will use prediction analysis based on prior work from our partner to predict likely compositions and then fabricate exemplar compositions to home in on the preferred composition(s).  We will evaluate the properties of the fabricated chalcogenide glasses to determine the appropriate composition.  In a follow-on Phase II effort, we will enhance the material's thermo-mechanical properties to enable it to survive higher laser power levels.
