Abstract
A negative‐branch confocal unstable resonator has been found to significantly improve the beam quality of a coaxial flashlamp‐pumped rhodamine 6G dye laser. In a performance comparison with a conventional parallel‐plane mirror resonator, over an order‐of‐magnitude increase in laser beam radiance has been measured. The negative‐branch unstable resonator demonstrated relatively uncritical alignment sensitivity.Keywords
