Single-frequency output from a unidirectional, out-of-plane, all-solid-state Nd:YAG ring resonator is demonstrated; the setup can be readily operated at both 1064 and 1319 nm with an end-pumping configuration. High multimode slope efficiencies of 42% were observed at 1064 nm, giving a maximum output power of 1.32 W. A maximum single-frequency, TEM00 output at 1319 nm of 650 mW was achieved with initial slope efficiencies of 17%. External enhancement cavity frequency doubling in LiB3 O5 gave a total single-frequency, TEM00 output power of 18 mW at 659.5 nm.
