Filed: 1982-05-13
Abstract: PURPOSE:To equalize the arc discharging route especially by trigger pulses by a method wherein a magnetic field is supplied in the direction perpendicular to the area to which the electron are moving in case of flashlamp discharge. CONSTITUTION:An N-pole piece 14 and S-pole piece 15 are respectively provided on one polarity side and the other polarity side of a flash lamp 3. When the lamp 3 is supplied with trigger pulses, gas molecules are excited by electrons generated by cathode surface to discharge arc making electron groups move around. In such a case, specific electromagnetic force is exerted for any electrons moving in the direction different from the direction of the magnetic field. This electromagnetic force exerting in the direction perpendicular to the direction of movement, the electrons receiving centripetal force start circular movement in the magnetic field reducing the radius of the circular movement inversely proportional to the degree of magnetic flux density. When an adequate magnetic field is supplied, a circular orbit arc discharge route is formed by the diameter of lamp 3 to lead the main discharge. Through these procedures, the luminous density distribution may be satisfactorily equalized further equalizing the excitation distribution in the laser active material 2 to make the intensity and distribution of laser beams remarkably stable extending the lamp life.
