  • The phase of a laser pulse is usually random, which prevents its use for phase-resolved measurements. Here, the authors seed a quantum cascade laser with coherent terahertz pulses, forcing laser action to start on a fixed phase. This kind of laser could be used as a source in time-domain spectroscopy.
