摘要： A magnetic coupling mechanism which can transmit rotational force of a motor with high efficiency and is simple in mechanism and unlikely to damage bearings, etc. and also unlikely to contaminate a laser gas, and in which flakes from plating or the like will not cause an operational abnormality. The magnetic coupling mechanism transmits rotational force from a motor shaft outside a laser chamber filled with a laser gas to a shaft of a gas-circulating fan in the laser chamber to rotate the fan. A first magnet group is provided on an inner peripheral surface at one end of the motor shaft. A second magnet group is radially coupled to the first magnet group through a ceramic partition constituting a part of the wall of a container of the laser chamber. The second magnet group is provided on the outer peripheral surface of the fan shaft.

摘要： The diameter of the spot of the light output from a laser diode is reduced through a coupled optical system so as to be smaller than the incidence aperture of a tapered total reflection rod. The light output from the coupling optics is focused into the incidence aperture of the total reflection rod. The total reflection rod is equipped with a smaller emission aperture than the diameter of the incidence aperture and further reduces the spot of the focused light. That is, the light passing through the total reflection rod is reduced to a smaller diameter while being totally reflected internally. A laser medium is in optical contact with the emission aperture of the total reflection rod and is pumped by the light which is output from the total reflection rod.
