We are currently being funded by the Joint Technology Office (JTO) and the Air Force to develop improved laser windows for use with next-generation high-power lasers. As part of this research, we are using new glass compositions to develop higher-quality glass for lasers operating over a range of wavelengths in the near- and mid-infrared regions. These multi-year R&D projects, totaling in the millions of dollars, will enable IFS to remain at the forefront of the military optics technology field for years to come.
