Nonequilibrium Semiconductor Disk Laser Theory and Simulation: Robust, Novel Multi-Functional Source forFemtosecond Pulsed and Multi-Wavelength CW Generation
Abstract
Semiconductor disk lasers (SDL) or equivalently vertical external cavity semiconductor lasers (VECSEL) offer fertile territory for developing fundamental theory and simulation tools while enabling the spin-off of a wide scope of new dual use technologies. The hitherto unavailable flexibility of individual quantum well placement within the active structure, not offered by edge emitters, now opens up a whole new set of functionalities and applications. Microscopic many-body interactions of electron-hole plasmas within individual semiconductor bands and their ultrafast relaxation via carrier-carrier and carrier-phonon scattering have been instrumental in contributing towards semiconductor lasers’ small size, weight, power (SWaP), and wavelength versatility in spanning the UV to the mid-IR bands. This will be a concerted effort towards establishing a self-consistent theoretical and simulation framework that integrates the microscopic physics with macroscopic contributions from other constituent materials making up a realistic laser cavity.
