Abstract:
Fundamental modelocking to generate short terahertz (THz) pulses and THz frequency combs from semiconductor lasers has become a routine affair using quantum cascade lasers (QCLs) as a gain medium. However, no demonstrations of harmonic modelocking have been shown in THz QCLs, where multiple pulses per round trip are generated when the laser is modulated at harmonics of the cavity’s fundamental round trip frequency. Here, using time resolved THz techniques, we show for the first time harmonic inj...     »
