Broad Tunable Quantum Cascade Lasers with Multiple Strongly coupled Upper Laser States
Princeton Docket # 10-2616 Broadly tunable QC lasers are ideal candidates for multi-analyte mid-infrared spectroscopy application. However, the maximum tuning range is usually limited by the inherently narrow gain spectrum of intersubband transitions. Princeton researchers have developed a ¿continuum-to-bound¿ QC laser, with two lower inje...
