Abstract
A high-efficiency plasma confining method, and a laser oscillating method of oscillating a laser, confine a plasma generated by entering a laser beam via an entry of a superconducting cylinder within the cylinder. The methods include the step of inhibiting diffusion or expansion in the radial or axial direction of the generated plasma by reducing the inside diameter of the cylinder between the entrance and an exit thereof. A magnetic line of force may be generated in the axial direction by winding a coil around the superconducting cylinder, to thereby confine the plasma. A laser oscillator for carrying out the method includes a superconducting cylinder, a supply mechanism for supplying a gas or a solid into the cylinder, and a laser irradiating mechanism. The inside diameter of the cylinder is reduced between an entry and an exit thereof, or the inside diameter of the cylinder is reduced at the entry and the exit thereof.
