Abstract

We report on efficient intracavity frequency doubling of a cw diode-pumped Nd:YAG laser on the F3/24I9/24 laser transition at 946  nm. The nonlinear crystal used in the experiments was a first-order quasi-phase-matched flux-grown KTiOPO4 crystal (period, 6.09 μm; thickness, 1  mm; length, 9  mm). The fluctuations in the generated second-harmonic wave were lower than 3% at output powers of as much as 500  mW. The overall optical-to-optical efficiency was 5.7%. A maximum output power of 740  mW of blue light was generated, which was stable for only 0.5  min. The decrease the output power at this power level was attributed to heating and thermal lensing in the periodically poled KTiOPO4 crystal. The short-term behavior of the second-harmonic wave exhibited switching between a cw mode and chaotic intensity fluctuations.
