Abstract
A laser beam generated between a total reflector and an output coupler is turned back by plural reflectors which are mounted in a discharge region along two main electrodes at 45.degree., and the discharge region is divided into plural divided discharge regions, thus, a diameter of an output laser beam is reduced to a diameter of the divided discharge regions.
