Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...

A simplified definition is the THD is the ratio of the sum of the power of all harmonic frequencies to the power of the fundamental frequency. If a circuit produced a perfect sine wave ...

High harmonic generation (HHG) is a highly non-linear phenomenon where a system (for example, an atom) absorbs many photons of a laser and emits photons of much higher energy, whose frequency is a ...

Asynchronous dual-comb generated in single laser cavity offer potent tools for simplified coherent measurements, owing to the common mode rejection which spares the sophisticated locking systems.

The asynchronously dual-comb generated in a single fiber laser cavity is a powerful tool for simplifying coherent measurements, as common-mode ...
