Abstract
A laser oscillator includes a discharge tube having a discharge area in which laser gas is excited and an output coupler and a rear mirror respectively arranged at both sides of the discharge tube. A first coating material having first reflectance is stacked as a dielectric multilayer on a first area including a radial center portion of a surface of the output coupler, which faces the discharge area, and a second coating material having second reflectance higher than the first reflectance is stacked as a dielectric multilayer on a second area around the first area.
