Abstract

A method of generating white light pulses (2) with a white light generation device (100) includes the steps of coupling pump laser pulses (1) into a white light generation crystal (10), generating the white light pulses (2) by an optically non-linear conversion of the pump laser pulses (1) in the white light generation crystal (10) and detecting at least one pulse characteristic of at least one of the pump laser pulses (1) and the white light pulses (2), wherein the white light generation device (100) is controlled using a control loop device (30) and the white light generation device (100) is adjusted in dependency on the at least one detected pulse characteristic. Furthermore, a white light generation device (100) for generating white light pulses (2) is described.
