Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
141 words
A LASER SYSTEM INCLUDING AN ACTIVE LASER ELEMENT, A FIRST REFLECTOR ASSOCIATED WITH ONE END OF SAID LASER ELEMENT, MEANS FOR ENERGIZING SAID LASER ELEMENT, AT LEAST ONE PIEZOELECTRIC ELEMENT, AT LEAST ONE SURFACE OF SAID PIEZOELECTRIC ELEMENT BEING OF VARIABLE CONTOUR WITH RESPECT TO THE OTHER END OF SAID LASER ELEMENT IN RESPONSE TO AN ELECTRIC FIELD ACROSS SAID PIEZOELECTRIC ELEMENT, A SECOND REFLECTOR ON SAID ONE SURFACE OF SAID PIEZOELECTRIC ELEMENT, SAID SECOND REFLECTOR FACING SAID OTHER END OF SAID LASER ELEMENT, AND MEANS FOR ESTABLISHING AN ELECTRIC FIELD ACROSS SAID PIEZOELECTRIC ELEMENT TO VARY THE CONTOUR OF SAID ONE SURFACE OF SAID PIEZOELECTRIC ELEMENT WITH RESPECT TO SAID OTHER END OF SAID ELEMENT WHEREBY THE CONTOUR OF SAID SECOND REFLECTOR IS VARIED BETWEEN NONPARALLELISM AND SUBSTANTIAL PARALLELISM WITH SAID FIRST REFLECTOR TO GATE THE OUTPUT OF SAID LASER.
