Advisor: Tober, Richard L.  (Richard.tober@us.army.mil  301-394-5756)
Keywords: Cascade infrared lasers, Optoelectronics; Molecular beam epitaxy; Communication lasers; Electronics

This research program focuses not only on the design, growth, characterization, and applications of infrared (IR) cascade lasers, but also on gaining knowledge of the fundamental physical properties that affect their performance. The goal of this work is to develop efficient lasers for use in chemical detection, free space communication, medical, and IR-countermeasure applications. Research opportunities exist for widely ranging topics such as molecular beam epitaxy growth, device design and fabrication, electronics, theoretical analysis, and even application engineering. Recent studies have focused on laser loss mechanisms and thermal characteristics, and the development of novel lasers designs.
