Abstract
A surgical laser system is provided with improvements to allow it to operate at higher power levels without beam divergence. The improvements include a beam expansion telescope in the optical path of the beam and modifications to the optical cavity and the lasing medium. The modifications include imposing a negative curvature on one or both ends of the rod, configuring the optical cavity as a positive-branch unstable resonator, and providing at least one intra-cavity shutter.
