Abstract

We report a laser cavity that has a ring as its output mode. The radius of the ring can be scanned by tuning the laser frequency. This design can be implemented in any tunable laser with large gain and can be useful when ring illumination patterns are needed. As an example, we demonstrate this new cavity configuration by using a side-pumped grazing-incidence dye laser.
