High-efficiency and narrow-linewidth operation of a two-crystal β-BaB2O4 optical parametric oscillator

We report a novel, two-crystal, walkoff-compensated optical parametric oscillator design using β-BaB2O4, which significantly improves the performance of the device. The oscillator is pumped at 354.7 nm and is tunable throughout 0.42–2.3 μm with overall conversion efficiencies as high as 32%. We also...

Description
Summary:We report a novel, two-crystal, walkoff-compensated optical parametric oscillator design using β-BaB2O4, which significantly improves the performance of the device. The oscillator is pumped at 354.7 nm and is tunable throughout 0.42–2.3 μm with overall conversion efficiencies as high as 32%. We also report on demonstration of linewidth narrowing in the same β-BaB2O4 oscillator, obtaining linewidths as narrow as 0.3 Å.
