High resolution frequency study and phase-locking have been performed on terahertz quantum-cascade vertical-external-cavity surface-emitting-lasers at 2.5 THz and 3.4 THz. A subharmonic diode mixer is
Abstract Pendulum clocks and metronomes have in common the fact that they are self-excited oscillators, exhibiting stationary oscillations where an external energy input compensates losses due to damp
The supplement, Text S1, contains a variety of material that is designed to provide further insight for the more curious reader, further methodology for the more technical reader, and further evidence
