Mode-locking of a CW laser 1 Introduction
... It was stated above that the pulse width is proportional to the inverse of the gain bandwidth. In fact, the transform limit on the time-bandwidth product is ∆τ ∆νg = .44 for the case of Gaussian pulses/Gaussian gain profile.1 The quantities ∆τ and ∆νg are measured as the full width at half maximum. ...

Some problems with connecting renewable energy sources to the grid
... In this section, the details of how to implement a synchronverter will be described. A simple DC/AC converter (inverter) used to convert DC power into three-phase AC (or the other way round) is shown in Figure 3. It includes three inverter legs operated using pulse width modulation (PWM) and LC filt ...
