Amplitude modulated laser transmitter

Claim 1

APPARATUS FOR TRANSMISSION OF A N AMPLITUDE MODULATED RADIATION BEAM OF OPTICAL FREQUENCY PRODUCED BY THE STIMULATED EMISSION OF RADIATION, SAID APPARATUS COMPRISING A LASING MEANS FOR EMITTING A COHERENT RADIATION BEAM OF ELECTROMAGNETIC WAVE ENERGY OF OPTICAL FREQUENCY WHEN SUPPLIED WITH CURRENT PULSES: PULSING MEANS FOR STORING ELECTRICAL ENERGY AND PERIODICALLY DELIVERING THE ENERGY IN THE FORM OF CURRENT PULSES TO SAID LASING MEANS TO PRODUCE SAID RADIATION BEAM, SAID PULSING MEANS COMPRISING AN ELECTRICAL ENERGY STORAGE NETWORK AND AN INTERMITTENT SWITCH MEANS INTERPOSED IN CIRCUIT BETWEEN THE STORAGE NETWORK AND THE LASING MEANS, SAID SWITCH MEANS BEING OPERATIVE TO PERIODICALLY COUPLE SAID ENERGY STORAGE NETWORK TO SAID LASING MEANS AT REGULAR INTERVALS FOR THE DELIVERY OF CURRENT PULSES THERETO; AND MODULATING MEANS INTERPOSED IN SERIES BETWEEN SAID SWITCH MEANS AND SAID LASING MEANS FOR MODULATING THE AMPLITUDE OF CURRENT PULSES DELIVERED TO THE LASING MEANSA FROM SAID ENERGY STORAGE NETWORK IN ACCORDANCE WITH THE AMPLITUDE VARIATIONS OF AN AUDIO VOLTAGE SIGNAL WHEREBY SAID LASING MEANS EMITS A SERIES OF AMPLITUDE-MODULATED RADIATION PULSES AT CONSTANT REPETITION RATE.
