A repetitively pulsed CO/sub 2/ laser facility was developed for testing annular resonators. The large-aperture device exhibits generally uniform gain over an annular region of 18-cm outer and 10-centimeter inner diameter. The half-symmetric unstable resonator with internal axicon (HSURIA) was tested at equivalent Fresnel numbers up to 4.5. This resonator design incorporates a W-axicon mirror beam compactor that transforms a cylindrical mode region into an annular mode region. Two HSURIA configurations were evaluated (1) with a rear conical mirror and (2) with a rear flat mirror in the annular leg.
