Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
115 words
IN A CONTROL SYSTEM FOR LASERS, MEANS FOR GENERATING A LASER OUTPUT INCLUDING AN ACTIVE CONTINUOUS WAVE LASER ELEMENT HAVING END REFLECTORS, AT LEAST ONE OF SAID REFLECTORS BEING SPACED AT A DISTANCE FROM SAID LASER ELEMENT, THE SPACE BETWEEN SAID REFLECTORS DEFINING AN OPTICAL CAVITY, A LIQUID ULTRASONIC CELL POSITIONED IN SAID OPTICAL CAVITY BETWEEN SAID LASER ELEMENT AND SAID SPACED REFLECTOR WHEREBY THE LASER OUTPUT PASSES THROUGH SAID CELL, MEANS FOR GENERATING AN AMPLITUDE MODULATED SIGNAL, AND MEANS FOR APPLYING SAID SIGNAL TO SAID CELL TO GENERATE AN AMPLITUDE MODULATED WAVE WITHIN SAI CELL, SAID LASER OUTPUT BEING INTENSITY MODULATED IN ACCORDANCE WITH SAID SIGNAL AS SAID LASER OUTPUT PASSES THROUGH SAID CELL.
