We propose a design for an optical resonator suited to using large-bore active media. The resonator consists of a pair of waxicons, so we call it a “wwaxicon optical resonator.” The resonator is considered a conventional (solid) resonator surrounded by coaxial annular resonators. A numerical simulation of the resonator designed for use in a commercial laser is performed. It is found that parasitic oscillation modes can be suppressed by the use of an spatial-frequency filter. The resonator exhibits oscillation in the transverse mode and produces twice as much output power as a sevenfold multipass stable optical resonator.
