Abstract
An energy quantity control method usable with a pulse energy producing source for successively emitting energy pulses of an energy quantity variable with time, wherein a control parameter for the pulse energy producing source is adjustable to control an energy quantity of an energy pulse, the method including determining, on the basis of a difference between a desired value for integrated energy quantity of energy pulses and an actually measured value for the integrated energy quantity, a desired value for a subsequent energy quantity to be provided subsequently by a subsequent energy pulse, and adjusting the control parameter on the basis of a difference between the desired value for the subsequent energy quantity to be provided subsequently by the subsequent energy pulse and an actually measured energy quantity provided by a last-emitted energy pulse.
