Publication on short pulse generation from THz QCLs

A paper on generating short pulses from QCLs has been published in Optica by the group at CNRS-LPA. The authors bring new insights into the QCL modelocking and show, contrary to popular believe, that the ‘active microwave’ modulation is the key parameter that determines the pulse duration rather than the QCL bandwidth or ultrafast dynamics. This will now impact the future direction of the ULTRAQCL project. The full publication can be accessed here
