摘要： PROBLEM TO BE SOLVED: To provide a light intensity modulated laser device which is stabilized in output power and output position at the same time and restrained from becoming large in size as a whole, even if it is composed of a solid-state laser device and a modulation device.

摘要： PROBLEM TO BE SOLVED: To obtain a strongly modulated second harmonic by a method, wherein the second harmonic is generated only when the laser ray wavelength of an LD is in the phase-matching allowable wavelength range of a wavelength conversion means, and the second harmonic is reduced to almost zero in output, when the laser ray wavelength of an LD is out of the phase-matching allowable wavelength range. SOLUTION: A domain inversion element has a phase-matching allowable wavelength width to phase-match only with the laser rays of certain wavelengths out of laser rays of variable wavelength range emitted from an LD. The domain inversion element having a phase-matching allowable wavelength width of λn to λ1 is used. In this case, only the laser rays of wavelengths λn to λ1 out of laser rays of variable wavelength range λ2 to λ1 and in a phase-matching allowable wavelength width are wavelength- converted to a second harmonic and outputted. On the other hand, laser rays of wavelengths less than λ2 to λ1 are not converted into wavelength, and a second harmonic intensity-modulated with the same frequency with laser rays emitted form the LD is generated. Through this setup, a second harmonic generating device which is very small in size, simple in structure, easily operated, and high in performance is capable of generating an intensity-modulated second harmonic.

摘要： PURPOSE:To prevent the cracking and incomplete phase transition of a thin film at the time of introducing oxygen by preheating this oxygen when the temp. of a substrate after film formation is reduced and oxygen is absorbed in the formed film in the case where a thin oxide superconducting film is directly formed on the substrate at a high temp. by a vapor growth method. CONSTITUTION:A crystalline film is formed on a substrate heated to 600-800 deg.C by sputtering in a film formation chamber and the formed film is cooled while slowly reducing the temp. of the substrate and holding the substrate at 400-600 deg.C if necessary. Oxygen is absorbed in the formed film by carrying out the cooling in oxygen and a thin oxide superconducting film as an end product is obtd. In this case, oxygen preheated to a prescribed temp. is introduced into the chamber and then cooled to room temp. after the lapse of a certain time. The temp. difference between the substrate and oxygen is reduced to prevent the instantaneous cooling of the formed film, the cracking and incomplete phase transition of the film due to rapid cooling can be prevented and a thin oxide superconducting film having satisfactory characteristics is obtd.

摘要： PURPOSE:To obtain an oxide superconductor excellent in superconductivity by filling silver in the void of the sintered bulky body of an oxide superconductor. CONSTITUTION:The void in the sintered bulky body of this oxide superconductor is filled with silver. The superconductivity of the superconductor is improved due to the presence of silver between the crystal grains and proximity effect, and the stability of the bulky body and consequently the stability in superconductivity are improved. When the void is narrowed and difficult to fill, the density of the sintered bulky body is lowered to enlarge the void, and the lowering of the superconductivity or stability due to the lowered density is sufficiently compensated by the improvement of superconductivity.

摘要： PURPOSE:To obtain an oxide superconducting layer excellent in superconductivity by sputtering by forming an oxide superconductor layer on a heated substrate by sputtering, cooling the layer while supplying gaseous oxygen and then etching the surface layer. CONSTITUTION:An oxide superconductor layer is formed on a heated substrate by sputtering, and then cooled while supplying gaseous oxygen. The surface layer of the formed layer is then etched and removed. The superconductor layer is naturally cooled after stopping the heating of the substrate or forcedly cooled by the gaseous oxygen. Since the oxide superconducting layer is produced in this way, an oxide superconducting layer with the insulating layer deteriorating superconductivity removed and excellent in superconductivity is formed.
