Abstract
We propose to develop a new type of a high performance, broadly, rapidly and electronically tunable monolithic, robust and low cost MWIR laser source. Our solution involves novel approaches to gain medium and the tuning mechanism. For gain medium, we will use a new quantum cascade laser (QCL) design combining high output power and efficiency with spectrally broad gain profile, allowing reliable tuning over>10% of the central wavelength. To achieve required broad tunability, we will use electrically controlled wavelength selective elements integrated directly into the laser chip. The specific approach we will pursue has worked successfully in near-IR diode lasers, and our simulations show that it is also well-suited for MWIR QCLs. We project developing devices that, at the end of Phase II, will be capable of delivering over 1 W in continuous wave at room temperature (CW/RT) mode with a tuning range of over 10% of the center wavelength at 4.6µm, with near diffraction-limited beam quality. Furthermore, we will apply our best-in-class QCL packaging technology that will result in robust devices that satisfy MIL-STD for vibration/shock and temperature tolerance and are ready for immediate integration into various Navy and other DoD applications.
