A Mode Locking Theory of the Nyquist Laser

Conference on Lasers and Electro-Optics, 2016
We derive a master equation for a mode-locked Nyquist laser that can emit a sinc function pulse. To derive the master equation, we used a method involving exponential perturbative expressions for gain, loss, and amplitude modulation, and a flat-top optical filter with edge enhancement.
