Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
77 words
A METHOD OF OPERATING AN OPTICAL MASER FOR CONTROLLING THE OUTPUT PULSE THEREOF WHICH COMPRISES EXCITING THE MASER MATERIAL TO A LEVEL BELOW THE STIMULATED EMISSION LEVEL WITH A RELATIVELY LARGE AMOUNT OF PUMPING ENERGY SUPPLIED OVER A RELATIVELY LONG TIME, SENSING THE EMISSION OF COHERENT LIGHT FROM THE MASER MATERIAL, AND THEN EXCITING THE MASER MATERIAL TO THE LEVEL FOR STIMULATED EMISSION WITH A RELATIVELY SMALL AMOUNT OF PUMPING ENERGY SUPPLIED OVER A RELATIVELY SHORT TIME.
Claim 2
Independent Claim
77 words

Claim 3
Independent Claim
100 words
A SYSTEM FOR OPERATING AN OPTICAL MASER FOR CONTROLLING THE OUTPUT PULSE THEREOF WHICH COMPRISES A BODY OF OPTICAL MASER MATERIAL, MASER MATERIAL EXCITATION MEANS OPERATIVELY ASSOCIATED WITH THE MASER MATERIAL, POWER SUPPLY MEANS OPERATIVELY CONNECTED TO THE EXCITATION MEANS FOR ENERGIZING THE EXCITATION MEANS, SENSING MEANS FOR DETECTING THE EXCITATION STATE OF THE MASER MATERIAL BY SENSING RADIATION EMITTED THEREFROM, AND SWITCHING MEANS COOPERATIVELY CONNECTED TO THE SENSING MEANS THE EXCITATION MEANS AND THE POWER SUPPLY MEANS FOR CONTROLLING THE EXCITATION STATE OF THE MASER MATERIAL BY CONTROLLING THE CONNECTION OF THE POWER SUPPLY MEANS TO THE EXCITATION MEANS.
