Phased array 1-to-N-way resonators can be relevant in the realization of high output powers from semiconductor laser arrays and have significant advantages over Talbot resonators. However, depending on the number of array elements, the intracavity power density on the output facet can be high, resulting in catastrophic optical mirror damage. We present a variant of the original design that overcomes these power density problems while maintaining the desirable phase-locking and power-combining properties.
