Intracavity second-harmonic generation of a diode-pumped Nd:YLiF 4 ring laser oscillating on the σ-polarized 4F 3/2-4I13/2 transition (λ ω∼1314nm) with a temperature-tuned periodically poled KTiOPO4 (ppKTP) crystal is reported, yielding up to 0.92 W tunable (λ = 656-658 nm) single-frequency output. Evidence of self-mode-locking via cascading nonlinearities is observed when the ppKTP is strongly phase mismatched.
