    摘要: A thin layer of ionic crystal is grown on a substrate. The crystal could be any type of ionic crystal, such as sodium chloride or potassium chloride. The crystal is a pure form of the chosen compound and may contain contaminants which would shift the wavelength of created color centers. On top of the first crystal layer, a second thin layer of a different type of crystal is deposited, such as lithium fluoride or sodium fluoride. When these two layers are radiated with gamma rays, they will each form color centers at the spots radiated. Because of the difference in crystalline properties of the two different ionic crystal centers, their color centers would be at different wavelengths. Each of the two separate ionic crystals will emit light at different characteristic wavelengths when illuminated at their unique absorption frequencies. Each layer can be made to lase separately. The top layer has an absorption energy greater than that of the bottom layer, so that the layer energy of the bottom layer absorption peak will pass through the top layer and be absorbed only by the bottom layer. There are many ways of forming F-centers in the two superimposed layers, such as by the use of selective gamma radiation by heating of an anion layer of the particular compound and then depositing the second ionic crystal on the first ionic crystal and then depositing an anion layer on the second crystal and then heating to produce a structure which will lase it to the different frequencies.

    摘要: A solid state, laser light control device (20, 30) and material (10), and methods of producing same. The device (20, 30) and material (10) consist essentially of a host material (14) which contains: a dopant species (16) at a first valence state (a), the concentration of which increases with distance from the surface (18); and the same dopant species (16) at a second valence state (b), the concentration which decreases with distance from the surface (18). The method comprises the steps of: obtaining a doped solid state material (14); exposing the solid state material (14) to elevated temperature, for a period of time, in an oxidizing or reducing atmosphere. The elevated temperature and time of exposure are selected to change the valence state (a) of the dopant (16) in direct proportion to distance from the surface (18) of the solid state material (16). What is thereby produced is a solid state device (20, 30) in which the concentration of the dopant 16 at the second valence state (b) decreases with radius, the concentration of the dopant (16) at the first valence state (a) increases with radius, and the sum of these concentrations remains constant.

    摘要: Refractory oxide crystals suitable for use in tunable lasers and a method for preparing the same are provided. The crystals are characterized by high quantum efficiency, high thermal stability, good crystal transparency, and a high percentage of useful luminescence. The method for preparation of the crystals involves removing substantially all the hydrogen, thermochemically reducing the crystal's oxygen content to produce oxygen (anion) vacancy defects, and subsequently irradiating the crystal with electrons to inactivate trace H.sup.- ions so that an increased amount of short lived F.sup.+ luminescence is produced when the crystal is optically excited.

    摘要: A method of manufacturing a diamond laser crystal having an excellent laser efficiency is performed by first, preparing a synthetic type Ib diamond containing at least 60 volume percent of a (111) plane growth sector (43) is prepared. This synthetic diamond is then thermally treated under high temperature/high pressure, so that type Ib nitrogen contained in the synthetic diamond is converted to type IaA nitrogen. Thereafter an electron beam is applied to the synthetic diamond in order to generate vacancies in the synthetic diamond. Finally annealing is performed on the synthetic diamond to form H3 centers by coupling the type IaA nitrogen atoms contained in the synthetic diamond, with the vacancies. According to this method, the H3 centers can be formed in the synthetic type Ib diamond at high concentration, while formation of NV centers which become an obstacle to laser action, can be suppressed.

    摘要: Vibrational emission from molecular defects in ionic crystals can be realized by dilute diatomic molecular defects such as, e.g., CN.sup.- molecules in alkali halide crystals. After association of F-centers to the CN.sup.- molecules, forming a new F-center/molecular defect pair, the emission can be pumped by optical F-center excitation through electronic-vibrational coupling. Using this coupling mechanism, laser action in the near infrared wavelength region is obtained between vibrational energy levels of the molecules while pumping the F-center/molecule defect in the visible wavelength range. The laser crystals are prepared by additively coloring a CN.sup.- doped alkali halide crystal and exposing the colored crystal to light having a wavelength capable of being absorbed by the electronic F-center/molecule defect transition.
