  • Infrared generation in semiconductor lasers
    Patent number: 6782020
    Abstract: Infrared generation is disclosed. A first laser field having a first frequency associated with a first interband transition is generated. A second laser field having a second frequency associated with a second interband transition is generated. The generation of the first laser field occurs substantially simultaneously with the generation of the second laser field. A third laser field is generated from the first laser field and the second laser field. The third laser field has a third frequency associated with an intersubband transition. The third frequency is substantially equivalent to a difference between the second frequency and the first frequency.
    Type: Grant
    Filed: September 10, 2001
    Date of Patent: August 24, 2004
    Assignee: The Texas A&M University System
    Inventors: Marlan O. Scully, Alexey A. Belyanin, Vitaly V. Kocharovsky, Vladimir V. Kocharovsky
