Abstract
The invention relates to a method for transferring the wave front of primary light pulses with a specifiable first pulse duration and/or energy to secondary light pulses with a specifiable second pulse duration and/or energy. For an easy realization of a wave front transformation of this type, it is suggested according to the invention to store respectively in a first time segment the wave fronts of the primary light pulses with the aid of reference light pulses as spatial hologram in a holographic memory. In a following second time interval, this stored, spatial hologram is then read out with the aid of reconstruction light pulses, having the second pulse duration and energy, wherein the reconstruction light pulses for reading out the hologram have the same wavelength and wave front as the reference light pulses.
