Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
158 words
METHOD OF DETECTING ELECTROMAGNETIC ENERGY AT ONE FREQUENCY BY THE DETECTION OF ELECTROMAGNETIC ENERGY AT ANOTHER FREQUENCY, WHICH COMPRISES: EXCITING AN ACTIVE MEDIUM TO PRODUCE A FIRST POPULATION INVERSION BETWEEN UPPER AND LOWER ENERGY LEVELS IN AN ATOMIC SYSTEM OF SAID MEDIUM, AND A SECOND POPULATION INVERSION BETWEEN ONE OF SAID LEVELS AND A THRID ENERGY LEVEL OF SAID ATOMIC SYSTEM; SETTING UP AT LEAST ONE OPTICAL MASER OSCILLATION, SAID OSCILLATION PRODUCING RADIATION AT SAID OTHER FREQUENCY WITH AN INTENSITY DEPENDENT UPON THE DIFFERENCE IN POPULATION BETWEEN SAID UPPER AND LOWER ENERGY LEVELS; EXPOSING SAID OSCILLATING MEDIUM TO RADIATION AT SAID ONE FREQUENCY WHICH IS EFFECTIVE TO INDUCE TRANSITIONS BETWEEN THE ENERGY LEVELS OF SAID SECOND POPULATION INVERSION THEREBY TO ALTER THE DIFFERENCE IN POPULATION BETWEEN SAID MASER ENERGY LEVELS AND CHANGE THE INTENSITY OF RADIATION AT SAID OTHER FREQUENCY; AND SENSING THE RADIATION AT SAID OTHER FREQUENCY AS AN INDICATION OF THE RADIATION AT SAID ONE FREQUENCY.
