[ALPS15-02] Improvement of efficiency of walk-off compensated β-BaB2O4 using room-temperature bonding

We found that only one of four manufacturers could fabricate β-BaB₂O₄ plates with small deviations from the phase-matching angle. Walk-off compensating structures using these plates improved the wavelength-conversion efficiencies.
