Abstract
A source of electromagnetic radiation including an output, means for generating a drive signal derived from a regenerative feedback signal generated from a portion of said output, further characterized in that an electrical signal obtained from said portion of said output is passed through a narrow bandpass filter in generating said regenerative feedback signal, and means for modulating said electromagnetic radiation within the cavity when the modulating means is driven by said drive signal is disclosed together with a method of generating short pulse electromagnetic radiation signals including operating a electromagnetic radiation source having an output, generating a drive signal derived from a regenerative feedback signal generated from a portion of said output, further characterized in that said portion of said output is passed through a narrow bandpass filter in generating said regenerative feedback signal, and, modulating said electromagnetic radiation, said drive signal derived from a regenerative feedback signal generated from a portion of said output.
