摘要： A transverse type gas laser oscillator includes a receptacle for containing a gas as a laser medium, a pair of electrodes disposed to be parallel to each other on opposite sides of the receptacle so that an electric field is established for generation of AC discharge when a high-frequency voltage is applied to them, and a pair of permanent magnets disposed so as to form a magnetic field intersecting a direction of the electric field established between the electrodes, or a pair of coils excited by a DC voltage. Consequently, ionization of the gas excited by the electric field is increased by the magnetic field.

摘要： A gas laser device includes a high frequency power source for generating a high frequency output voltage and a pair of electrodes positioned sandwiching a discharge gap through which laser gas circulates. The pair of the electrodes are connected to the high frequency power source for applying the high frequency output voltage across the electrodes to achieve discharge in the discharge gap and to thereby generate laser light. Each of the electrodes includes an electrode element, a capacity coupling control element provided on either side of the electrode element, and a dielectric shell. The dielectric shell surrounds the electrode element and the capacity coupling control element, therefore the discharge occurs between the dielectric shells of a pair of the electrodes. The dielectric constant of the capacity coupling control means is lower than that of the dielectric shell.

摘要： An optical fiber has a core structure and a first coating layer covering the core structure. The optical fiber, after being twisted, is covered at its outer side with a second coating layer. The second coating layer is higher in Young's modulus than the first coating layer. As a result, the twisting of the optical fiber is stably retained by the second coating layer. Further, an outer force coming from the second coating layer is absorbed by a soft first coating layer, so that no compressive force acts on a core and cladding in the optical fiber.

摘要： In a gas laser, the surface of either or both of discharge electrodes are formed from titanium oxide which provides fine sputtering proof. The discharge electrodes are formed from titanium as a base material having an oxidized surface. Alternatively, the discharge electrodes are formed from molybdenum as a base material with titanium coated and the surfaces are oxidized. In the gas laser of the direct current discharge type, the cathode is formed as described above. Both of cathode and anode are formed as described above in the gas laser of the alternate current discharge type.
