Laser Pulses Power Energy Equations - Thorlabs
www.thorlabs.comPulse Energy( q[ J ]) A measure of one pulse's total emission, which is the only light emitted by the laser over the entire period. The pulse energy equals the shaded area, which is equivalent to the area covered by diagonal hash marks. Average Power ( | [ W ]) The height on the power axis, if the energy emitted by the pulse
