| Abstract Scope |
The advancement of lasing technology over the last century has resulted in the generation of high energy lasers (HELs) and other directed energy weapons (DEWs) as an offensive warfighting strategy. As a defensive advantage, the development of a reusable optical limiter coating with broadband reflection is essential to protect military components subject to targeted attacks. The coatings from this study were engineered to exhibit an on/off nonlinear optical behavior that allows for transmission at a specific wavelength at low incident irradiances, and high reflection at high incident irradiances. The optical limiter coating is comprised of a nonlinear material deposited within the cavity of a Fabry-Perot filter consisting of two mirrored quarter wavelength distributed Bragg reflectors. In this study, nitride and oxide based material systems were deposited utilizing magnetron sputtering and electron-beam physical vapor deposition, respectively. Future development of optical limiters may provide protection of communication systems and electronic devices. |
