A resonator is provided that includes opposing mirrors arranged substantially parallel to each other and separated to confine reflections for gain. A gain medium is between the opposing mirrors. A pump pumps the gain medium. At least one microrefractive element, or tens, hundreds, thousands, millions or more, stabilizes the resonator. The refractive element is disposed between the opposing mirrors and is configured to support a laser beam at a position of the refractive element. A method for producing laser light directs pump light onto one or a plurality of microrefractive elements. Reflections from the one or a plurality of microrefractive elements are confined in a resonator volume. Gain is provided in the resonator volume. Laser energy is emitted from the resonator volume.
