A multi-end-pumped nonplanar ring laser with a two-mirror resonator has been demonstrated. Two important parameters of the beam loops are described, and simulation diagrams of the beam loops are shown. Using an output coupler with a fan-shaped distribution in reflectivity, multi-end-pumped operation with the output beam from a single point has been achieved, and the experimental results show that the laser could be multi-end-pumped to reduce thermal effects and multiply the fracture limit of the laser crystal.
