Abstract

Tapered unstable resonator lasers incorporating laterally finite mirrors are reported. By reducing the lateral extent of mirrors, cavity losses may be shifted from internal losses (contributing to scattering and absorption) to mirror losses (contributing to output power). Design of these cavities will be discussed and evaluated. Experimental data substantiates theoretical analysis, showing an increase in slope efficiency of 40% over conventional infinite aperture tapered lasers.
