Abstract

A variety of resonator designs that may be scalable to large high-power HF overtone lasers are discussed. Multipass resonators with multiple turning mirrors and with common turning mirrors are included in the discussion. Geometric optics are utilized in analyzing these concepts. Emphasis is placed on gain saturation, amplified-spontaneous-emission and parasitic control by gain segmentation, alignment tolerances, and diffractive beam spillage. It is concluded that for moderate powers, the multipass concept with separate turning mirrors is preferable, while for higher powers, a concept with common turning mirrors may be chosen.
