  • High stability ultra-short sources of electromagnetic radiation
    Patent number: 5598425
    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 feed

  • Regenerative optical pulse generator
    Patent number: 5390202
    Abstract: Filtered regenerative feedback is used to modulate a laser or other source of electromagnetic radiation to generate optical pulses whose amplitudes and repetition rates are continuously tunable. The technique is in principle applicable to any source of electromagnetic radiation and is especially effective for semiconductor diode lasers.
