Pulse Energy( q[ J ]) A measure of one pulse's total emission, which is the only light emitted by the laser over the entire period. Pulse Width (PW) is the elapsed time between the rising and falling edges of a single pulse. So this leads us to define two different types of power. $$P_0 =\frac{2\mathcal{E}}{\Delta t}\sqrt{\frac{\ln2}{\pi}}\approx\frac{0.94\mathcal{E}}{\Delta t}. The figures are averages, so use them as a general guide.
