Research output: Contribution to journalConference articlepeer-review


An extended-cavity resonator with an aspheric third mirror aligned collinear to a standing-wave two-mirror resonator is studied. A number of benefits of this new cavity design such as improved mode selectivity and mode shaping were predicted by simulation. An experiment was performed with a Nd:YVO4 laser system. With an optimized aspheric third mirror, this three-mirror solid-state laser has an experimentally measured modal discrimination of 1.43 and oscillates in the designed fundamental Gaussian mode. The M2 of the cavity mode was measured to be 1.02. Applications of aspheric feedback mirrors in other advanced laser resonators are also briefly discussed.
