Efficient Mid-Wave Infrared Lasers (EMIL)
Abstract
The Efficient Mid-Wave Infrared Lasers (EMIL) program evaluated efficient solid-state coherent sources that can cover the atmospheric transmission bands in the mid-wave infrared (MWIR; 3-5 micrometers). Infrared countermeasure (IRCM) systems in particular depend on intense sources at these bands. The current generation IRCM systems utilize diode-pumped Thulium (Tm) lasers used to pump optical parametric oscillators, most commonly based on zinc germanium phosphide. The lasers developed in this program operate across the three relevant bands within the MWIR at 10 W power with wall plug efficiencies of at least 10 percent. By virtue of the enormous volumetric reduction (100-1000 times), power reduction (ten times), and superior pulse format (cw-operation), such sources are enabling new architectures and approaches permitting IRCM systems to be deployed on platforms (e.g., rotocraft) which are highly vulnerable to Man Portable Air Defense Systems and other threats but for which current IRCM systems are prohibitive or are inadequate (e.g., unable to defeat staring sensors).
