Optical maser system for production of repetitive short pulses of coherent light

Claim 1

A SYSTEM FOR THE PRODUCTION OF REPETITIVE PULSES OF COHERENT LIGHT WHICH CONSISTS OF A BODY OF MASER MATERIAL AT THERMAL EQUILIBRUM LEVEL, A PULSE GENERATOR FOR GENERATING A SERIES OF PULSES OF ELECTRICAL ENERGY WITH A TIME INTERVAL BETWEEN PULSES WHICH IS SUBSTASNTIALLY LESS THAN THE FLUORESCENT RELAXATION TIME OF THE MASER MATERIAL, AND A SINGLE FLASH TUBE CONNECTED TO THE PULSE GENERATOR FOR ENERGIZATION BY THE PULSES OF ELECTRICAL ENERGY AND PRODUCTION OF A SERIES OF PUMPING LIGHT PULSES OF INSUFFICIENT ENERGY TO ELEVATE SAID MASER MATERIAL TO THE THRESHOLD FOR STIMULATED EMISSION HAVING A TIME INTERVAL BETWEEN PULSES WHICH IS SUBSTANTIALLY LESS THAN THE FLUORESCENT RELAXATION TIME OF SAID MASER MATERIAL, SAID FLASH TUBE BEING COOPERATIVELY ASSOCIATED WITH SAID MASER MATERIAL FOR CONTINUOUSLY APPLYING THE PULSES OF LIGHT ENERGY TO THE MASER MATERIAL FOR PUMPING SAID MASER MATERIAL TO THE THRESHOLD FOR STIMULATED EMISSION BY STEPWISE ELEVATION OF QUANTUM STATE THEREOF AND CONTINUOUSLY PRODUCING A SERIES OF PULSES OF COHERENT LIGHT THEREFROM CORRESPONDING TO THE SERIES OF PUMPING LIGHT PULSES.
