Claim 1
Independent Claim
203 words
APPARATUS FOR GENERATING AN ELECTROMAGNETIC WAVE E3 OF A FREQUENCY F3 FROM A PLURALITY OF ELECTROMAGNETIC WAVES E1, E2,... OF FREQUENCIES F1, F2,... WHICH FREQUENCIES F1, F2,... MAY BE EQUAL, AND WHICH FREQUENCY F3 IS A LINEAR COMBINATION OF THE FREQUENCIES F1, F2,... SAID APPARATUS COMPRISING A BODY OF NON-LINEAR DIELECTRIC MATERIAL, A PLURALITY OF LIGHT SOURCES OF FREQUENCIES F1, F2, ... RESPECTIVELY, SAID SOURCES BEING POSITIONED TO ILLUMINATE A COMMON REGION OF SAID BODY, SAID SOURCES BEING OF SUFFICIENT INTENSITY TO GENERATE IN THE BODY POLARIZATIONS VARYING NON-LINEARLY WITH THEIR INTENSITIES, SAID SOURCES GIVING RISE IN SAID REGION TO A POLARIZATION WAVE OF THE FREQUENCY F3 AND HAVING A WAVE NUMBER VECTOR WHICH IS A LINEAR COMBINATION OF THE WAVE NUMBER VECTORS OF THE ELECTROMAGNETIC WAVES IN SAID REGION FROM SAID SOURCES, SAID BODY HAVING A PLURALITY OF BOUNDARIES ENCOUNTERED BY SAID POLARIZATION WAVE, SAID BOUNDARIES SUCCESSIVELY ENCOUNTERED BY SAID POLARIZATION WAVE BEING SEPARATED BY PATH LENTHS FOR SAID POLARIZATION WAVE OVER WHICH THE DIFFERENCE BETWEEN THE PHASE CHANGE UNDERGONE BY SAID POLARIZATION WAVE AND THE ELECTROMAGNETIC WAVE OF FREQUENCY F3 WHOSE WAVE NUMBER VECTOR IS COLLINEAR WITH THAT OF SAID POLARIZATION WAVE AMOUNTS TO SUBSTANTIALLY N+-1/2 CYCLES, N BEING AN INTEGER.

Claim 3
Dependent Claim
121 words
APPARATUS FOR GENERATING AN ELECTROMAGNETIC WAVE E3 OF FREQUENCY 2F1 FROM ELECTROMAGNETIC WAVES OF FREQUENCY F1, SAID APPARATUS COMPRISING A BODY OF OPTICALLY LINEAR MATERIAL HAVING TWO OPPOSITE PLANE PARALLEL FACES, SEPARATE BODIES OF OPTICALLY NON-LINEAR MATERIAL DISPOSED IN OPTICAL CONTACT WITH EACH OF SAID FACES, AND AT LEAST ONE HIGH INTENSITY SOURCE OF LIGHT OF FREQUENCY F1 DISPOSED IN POSITION TO SEND A BEAM E1 INTO SAID BODY FOR SUCCESSIVE REFLECTIONS AT SAID BODIES OF NON-LINEAR MATERIAL FOR GENERATING AT EACH SUCH REFLECTION A POLARIZATION WAVE OF FREQUENCY 2F1, SAID BEAM BEING OF INTENSITY SUFFICIENT TO GENERATE IN SAID BODIES OF NON-LINEAR MATERIAL POLARIZATION WAVES INCLUDING A COMPONENT VARYING ACCORDING TO A POWER OF THAT INTENSITY HIGHER THAN THE FIRST.
