Abstract
A pyroelectric non-linear optical component for detection and frequency control of electromagnetic radiation is comprised of a body consisting of a monocrystalline orthorhombic magnesium barium fluoride (MgBaF.sub.4) and means for changing the optical properties of the body. The pyroelectric component may be used in electro-optical systems, such as laser systems, for frequency doubling or mixing of electromagnetic radiation, particularly in the ultraviolet spectral region and may include a pair of electrodes mounted on opposite surfaces of the component for applying a controlled voltage thereto.
Claims5
A pyroelectric non-linear optical component comprising a body consisting of morocrystalline orthorhombic magnesium barium fluoride (MgBaF.sub.4) and means for changing the optical properties of said body.
In an operational electro-optical system including a means for producing electromagnetic radiation in the infrared, visible and ultraviolet spectral regions and a means for frequency control of said electromagnetic radiation, the improvement comprising that said means for frequency control comprises a pyroelectric non-linear optical component comprised of a body consisting of monocrystalline orthorhombic magnesium barium fluoride (MgBaF.sub.4).
A method of obtaining a harmonic frequency of a basic frequency of electromagnetic radiation in the infrared, visible and ultraviolet spectral regions comprising:
- projecting electromagnetic radiation of a basic frequency through a pyroelectric non-linear optical component comprised of a body consisting of monocrystalline orthorhombic magnesium barium fluoride which emits a harmonic frequency of said basic frequency.
A method of detection and controlling a beam of electromagnetic radiation in the infrared, visible and ultraviolet spectral regions, comprising:
- projecting a beam of electromagnetic radiation through a pyroelectric non-linear optical component having a body composed of monocrystalline orthorhombic magnesium barium fluoride;
- and
- changing the optical properties of said body by applying a voltage to electrodes disposed on said body so that the characteristics of said beam are changed in response to the changes in the optical properties of said body.
