Paper Abstract

Presented is a study of a coaxial, hybrid-stable-unstable resonator for high power lasers. The coaxial configuration allows the realization of the outcoupling and rear mirror in one mechanical structure with the incorporation of an axicon mirror with retroreflective characteristics as an intra-cavity folding mirror. The design of the stable direction is investigated to optimize the set-up for best beam quality and minimized alignment sensitivity. Additionally, the instable direction is examined to achieve an even heat load on the mirrors. Simulations of the laser structure are performed and compared to measurements.
