Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
26 words
A non-linear optical component as defined in claim 1 wherein said means includes a pair of electrodes, each mounted on an opposing surface of said monocrystal.
Claim 2
Dependent Claim
48 words
In a laser system including means for producing electro-magnetic radiation in the infrared, visible and ultra-violet spectrum range and a means for frequency control of said electro-magnetic radiation, the improvement comprising that said means for frequency control comprises a non-linear monocrystal optical component composed of barium nitrite hydrate.
Claim 3
Independent Claim
52 words
A method of obtaining a harmonic frequency of a basic frequency of electromagnetic radiation in the infrared, visible and ultra-violet spectral region comprising: projecting electromagnetic radiation of a basic frequency through a non-linear optical component having a monocrystal composed of barium nitrite hydrate which emits a harmonic frequency of said basic frequency.
Claim 4
Independent Claim
76 words
A method of controlling a beam of electromagnetic radiation in the infrared, visible and ultraviolet spectral region comprising: projecting a beam of electromagnetic radiation through a non-linear optical component having a monocrystal composed of barium nitrite hydrate; and changing the optical properties of said monocrystal by applying a voltage to electrodes disposed on said monocrystal so that the characteristics of said beam are changed in response to the changes in the optical properties of said monocrystal.
