Paper Abstract

Power-scaling of optically pumped semiconductor lasers (OPSL's) using a resonator with multiple OPS chips is demonstrated. With a 3-chip cavity and intra-cavity second harmonic generation, we obtain 55W of TEM00 mode output at 532 nm and 66 W in multi-transverse mode. In addition, we describe the design of a periodic dynamically stable resonator that allows scaling to more than 4 chips and demonstrate that the output power scales with the number of chips in the cavity.
