Abstract

See full text

There is provided a slab amplifier including an optical system (48, 51) provided in a chamber (47) to allow a seed beam having entered from a first window into the space between a pair of electrodes (42, 43) to be repeatedly reflected between the space so that the seed beam is amplified to be an amplified beam; a first aperture plate (61) provided between the first window and the electrodes, and having an opening of a dimension equal to or greater than a cross-section of the seed beam and equal to or smaller than a dimension of the first window; and a second aperture plate (62) provided between the second window and the electrodes, and having an opening of a dimension equal to or greater than a cross-section of the amplified beam and equal to or smaller than a dimension of the second window.
