Abstract
A plasma is excited uniformly as a whole over the length of each slot. A laser oscillating apparatus is designed to excite a laser gas in a laser tube ( ) by introducing electromagnetic waves into the laser tube through a plurality of slots ( ) formed in a waveguide wall and generate a laser beam by resonating the light generated from the laser gas. A least one electrode ( ) is placed near the slot ( ). By giving a predetermined current density to the electrode ( ), the intensity distribution of light generated from the laser gas above the slot ( ) is controlled.
