Abstract
The invention relates to a method for producing radio frequency waves, whereby a pulse laser for producing light pulses having a predetermined spectrum of frequency modes and a predetermined recurrence frequency is operated. The light pulses of the pulse laser are detected by means of a detector device, and corresponding electrical output signals forming the radio frequency signals are produced. Said pulse laser is actuated in a stabilized manner by means of an optical reference signal in such a way that the recurrence frequency of the light pulse is fixed. The invention also relates to a radio frequency generator for implementing said method.
