Source: Nature The Kuizenga–Siegman Theory in Laser Physics The Kuizenga–Siegman theory is a theoretical framework used to calculate the pulse duration of an actively mode-locked laser. In this theory, two main mechanisms influence the duration of the circulating pulse: the modulator, which attenuates the pulse wings, reducing the pulse duration, and the gain medium, which […]
