Abstract: PROBLEM TO BE SOLVED: To continuously remove moisture, and always maintain a bed or the like in a dry condition by sandwiching a film of a hydrogen ion conductive solid electrolyte by an anode and a cathode, and providing a solid electrolytic element which generates oxygen by electrolytic reaction on the anode side and performs reducing reaction on the cathode side, in a holding body of the bed or the like. SOLUTION: When a holding body 7 such as a mat absorbs moisture such as sweat of the human body, this moisture enters a case 11 from respective air vents 12c and 12d. Since DC voltage is impressed between a cathode 19 and an anode 22 of a solid electrolytic element 15, water is electrolyzed on the anode 22 side, and humidity of an anode 22 side dehumidifying space reduces. A hydrogen ion of a cation generated at this time passes through a film 16 of a solid electrolyte, and on the other hand, an electron reaches the cathode 19 by passing through an external circuit, and generates water by consuming cathode 19 side oxygen. This water becomes steam, and is discharged outside from an air vent 12a. Air in the case 11 is heated by heating of the solid electrolytic element 15, and is returned in the holding body 7 through a filter 13.

Abstract: PURPOSE: To make the rising of a voltage pulse to be applied to an auxiliary electrode steep without delaying rising of a voltage of a main discharge electrode of a discharge excitation pulse laser device. CONSTITUTION: A reactor connected serially to a first charging capacitor 9 is composed of a first saturable reactor 19, and a second saturable reactor 21 is inserted in series with a second charging capacitor 12. After a floating inductance component and a resistance component of a switch 8 become the minimum, inductance of the second saturable reactor 21 is reduced first, and then inductance of the first saturable reactor 19 is reduced. Sharpness of rising of a voltage for corona discharge and main discharge 17 both can thus be set at high values, and preliminary electric dissociation is increased to set the main discharge 17 uniform, and increase injection energy to the discharge, thereby laser output and oscillation efficiency can be improved.

Abstract: PURPOSE:To improve the efficiency of laser oscillation by extending the advancement length of corona discharge, and allowing ultraviolet light emitted from the part where the corona discharge is the strongest to irradiate laser gas between the main electrodes. CONSTITUTION:A preionizing section is arranged so that the part where corona discharge is the strongest may be directed at a space between main electrodes 1 and 2 by extending the advancement length l of corona discharge 6. The amount of ultraviolet light is intensified by extending the advancement length lof the corona discharge 6. Particularly, the electrodes are laid out so that the ultraviolet light which is generated from near the starting point of the strongest corona discharge out of the corona discharge 6 may irradiate the space between the main electrodes and 2. This construction makes it possible to provide a uniform and main electrode 3 even when such gas having the strongest electron adhesion as F gas may be contained in laser gas and hence obtain a lateral discharge excitation pulse laser oscillation device capable of oscillating at the highest efficiency.

Abstract: PURPOSE:To enable high repetition operation by generating periodical trigger signals which generate high repetition pulse signal in a first period and stop the signals in a second period. CONSTITUTION:A trigger circuit 5 generate high repeat trigger pulses in a period t1 so as to generate laser beams 8 by discharge 3, and in the next period t2 it stops the oscillation so as to provide the period to blow off the effect of discharge 3 by gas flow 9. As a whole, with period t3, i.e., t1+t2 as one period, it repeats the operation. And the first period t1 is set shorter than three times the time which is required for laser output to settle to certain low output, and the second period t2 is set to the time which is required for the laser output in the next first period to be restored to the initial output. Hereby, high repeat becomes possible without being accompanied by enlargement of the device or lowering of pulse output.

Abstract: PURPOSE:To support a Fabry-Perot etalon(FP) without producing a distortion and prevent contamination due to degasification and the like by supporting only one side glass of the FP with U-shaped rings made of fluororesin. CONSTITUTION:An FP 7 for tuning wavelengths is disposed between a laser oscillator and a partial reflecting mirror. A closed vessel 8 where the FP 7 is housed is filled with a gas and is sealed with anti-reflection(AR) coating glass 9. Only one of glass materials out of two sheets of them which form the FP 7 is supported in the closed vessel 8 by means of U-shaped rings 27 made of a fluororesin. In other words, if two sheets of glass are supported simultaneously, surplus force equal to slippage acts upon and gaps between two sheets of glass produce distortions. As only one side mirror is supported in order to prevent the distortions, no distortion of FP 7 appears very much and no degasification occurs even though a laser beam makes irregular reflection and strikes upon the U-shaped rings 27. Such a supporting system thus prevents contamination of the FP 7.

Abstract: PURPOSE:To substantially eliminate variations in an output and a beam emitting direction even if an air gap etalon is replaced by setting an angle formed between two AR coating faces of the etalon to be inserted into a resonator to + or -4mrad or less. CONSTITUTION:A laser oscillator 1 has an optical resonator formed of a total- reflecting mirror 2 and a partial reflecting mirror 3, a light is amplified while it reciprocates in the resonator to become a laser beam 5. Here, an angle formed between two anti-reflection coating faces(AR coating faces) 6, 7 of an air gap type etalon 4 to be introduced into the resonator is set to + or -4mrad or less. Since the etalon 4 is so constructed as to become parallel flat plates as a whole, the beam 5 passing the etalon 4 is not varied in its emitting direction but slightly displaced in parallel. Thus, even when the etalon 4 is replaced, its emitting direction is not varied, and the alignment of the resonator is not altered, thereby eliminating the no emission of the beam.
