Diffractive resonators for solid-state lasers

Research output: Contribution to journalConference articlepeer-review


Previous experiment showed a diffractive-optic laser cavity consisting of a flat mirror and a single diffractive mirror for producing a flat-top laser beam. This paper shows that using a curved output mirror has several advantages. First, the cavity can be shortened substantially while still maintaining good discrimination against higher-order modes. Second, the total phase excursion can often be contained within 2π radians, eliminating the phase discontinuity present in the a diffractive structure. This makes it easier to coat the surface with multi-layer dielectrics for high reflection.
