> They made a laser pulse consisting of a bunch of different frequencies mixed together This is how ultra short pulses are made when the waves cancel out appropriately. Now I'm not sure if they are training a network to calculate the filter efficiently for even shorter pulses, or if the purpose is supposed to be an optical neural network, or why not both.
