    Abstract: An interferometric axial-mode-selective laser resonator in which one or more resonant prisms form the auxiliary resonator or resonators. Tandem vernier types may provide single-axial-mode operation in solid-state lasers in situations for which it was not previously feasible. In other embodiments a single prism resonator with three reflective surfaces forms a stable and tunable filter for wavelength and axial-mode selection. Wide-band output coupling modulation can be advantageously employed with a resonant prism of electro-optic material.

    Abstract: There is disclosed a source of coherent optical energy in which a plurality of lasers pumped to support multiple axial modes are restricted to either mutually phase-locked multiple-mode operation or synchronized single-mode continuous-wave operation by mutual coupling to a common resonator that is adapted to support an additive buildup of intensity from the lasers in a manner providing mutual mode-frequency locking. The common resonator is either a ring or is an interferometric resonator of relatively great free spectral range compared to that of the laser resonators. Mode-frequency selection is facilitated by active media providing strong mode competition and/or by a common resonator having one or more loss ports that contribute to a strong filtering characteristic.
