Abstract
Abstract A laser system emits a laser beam from a laser oscillator through a kaleidoscope to make intensity distribution of the laser beam uniform. This laser system is a scanning type in which a plurality of kaleidoscopes are bundled together to form a kaleidoscope bundle. The laser beam from the laser oscillator is scanned and is applied to the input ends of the respective kaleidoscopes of the kaleidoscope bundle successively.
