Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
98 words
DEVICE COMPRISING A CRYSTALLINE BODY CONSISTING ESSENTIALLY OF LINBO3, TOGETHER WITH MEANS FOR INTRODUCING A BEAM OF COHERENT PLANE POLARIZED ELECTROMAGNETIC RADIATION OF A FIRST FREQUENCY INTO THE SAID BODY AND MEANS FOR EXTRACTING FROM THE SAID BODY A BEAM OF COHERENT ELECTROMAGNETIC RADIATION OF A SECOND FREQUENCY, THE SAID BODY BEING POSITIONED SO THAT THE ANGLE DEFINED BY THE SAID INCOMING BEAM AND THE OPTIC AXIS IS SUCH THAT AN ORDINARY WAVE OF ONE OF THE SAID FREQUENCIES WITHIN THE SAID BODY IS PHASE-MATCHED TO AN EXTRAORDINARY WAVE OF ANOTHER OF THE SAID FREQUENCIES WITHIN THE BODY.
Claim 2
Dependent Claim
98 words
DEVICE COMPRISING A CRYSTALLINE BODY CONSISTING ESSENTIALLY OF LINBO3, TOGETHER WITH MEANS FOR INTRODUCING A BEAM OF COHERENT PLANE POLARIZED ELECTROMAGNETIC RADIATION OF A FIRST FREQUENCY INTO THE SAID BODY AND MEANS FOR EXTRACTING FROM THE SAID BODY A BEAM OF COHERENT ELECTROMAGNETIC RADIATION OF A SECOND FREQUENCY, THE SAID BODY BEING POSITIONED SO THAT THE ANGLE DEFINED BY THE SAID INCOMING BEAM AND THE OPTIC AXIS IS SUCH THAT AN ORDINARY WAVE OF ONE OF THE SAID FREQUENCIES WITHIN THE SAID BODY IS PHASE-MATCHED TO AN EXTRAORDINARY WAVE OF ANOTHER OF THE SAID FREQUENCIES WITHIN THE BODY.
Claim 3
Dependent Claim
110 words
DEVICE COMPRISING A PIEZOELECTRIC CRYSTAL CHARACTERIZED BY VALUES OF BIREFRINGENCE AND DISPERSION SUCH THAT ORDINARY AND EXTRAORDINARY RAYS OF DIFFERENT FREQUENCY COHERENT ELECTROMAGNETIC RADIATION MAY BE PHASE-MATCHED WITHIN THE SAID CRYSTAL, TOGETHER WITH MEANS FOR INTRODUCING INTO THE SAID CRYSTAL A PLANE POLARIZED FIRST BEAM OF COHERENT ELECTROMAGNETIC RADIATION, AND MEANS FOR EXTRACTING FROM THE SAID CRYSTAL A SECOND BEAM OF COHERENT ELECTROMAGNETIC RADIATION, THE SAID SECOND BEAM CONTAINING A COMPONENT HAVING A FREQUENCY DIFFERENT FROM ANY CONTAINED WITHIN THE SAID FIRST BEAM, AND TOGETHER WITH THERMAL MEANS FOR EFFECTING PHASE-MATCHING OF DIFFERENT FREQUENCY COHERENT ELECTROMAGNETIC RADIATION BY CHANGING THE RELATIVE VALUES OF BIREFRINGENCE AND DISPERSION WITHIN THE SAID CRYSTAL.
Claim 4
Dependent Claim
110 words
