Abstract

Intracavity second-harmonic generation of a diode-pumped Nd:YLiF4 ring laser oscillating on the σ-polarized F324I1324 transition (λω1314nm) with a temperature-tuned periodically poled KTiOPO4 (ppKTP) crystal is reported, yielding up to 0.92W tunable (λ2ω=656658nm) single-frequency output. Evidence of self-mode-locking via cascading nonlinearities is observed when the ppKTP is strongly phase mismatched.
