Far-Infrared Few-Cycle-Pulse Generation in Quantum-Well Heterostructures under Femtosecond Laser Pumping

摘要

It is shown that the resonant nonlinear-wave mixing in the semiconductor quantum wells under a femtosecond optical pulse excitation can be used for the generation of the utmost short mid/far-infrared pulses with a few- or even single-cycle duration defined by pump duration.
