Abstract :
Quantum Cascade Lasers are promising sources of Terahertz radiation. Picosecond pulses generation with these lasers is currently at its infancy and their detection is difficult. An intensity electro-optic sampling method is used here to demonstrate 19ps FWHM pulses from a QCL via active modelocking.
