Abstract
According to this invention the argon gas laser for emitting monochromatic light at 4880 .ANG. is provided comprising an elongated envelope with a capillary filled mainly with argon gas, an optical resonator comprising a high reflectance multilayer mirror and an output coupling multilayer mirror facing each other and disposed along the optical axis of the envelope. A cathode electrode and an anode electrode are disposed within the envelope for discharging the gas. Each mirror comprising alternate stacked layers of relatively high refractive index materials and relatively low refractive index materials. The high reflective mirror having a high reflectance band with a center wavelength .lambda..sub.0 containing a laser wavelength .lambda..sub.L within said band which satisfies the following expression:
