Abstract

YCa4O(BO3)3 has been found to be 90° phase-matchable for type-1 second-harmonic generation at 0.4168 µm along the z-axis at 20°C. The improved Sellmeier equations of YCa4O(BO3)3 that correctly reproduce our new experimental data for second-harmonic and sum-frequency generation in the 0.3547–1.9079 µm range are reported. In addition, the 90° phase-matching properties of GdxY1-xCa4O(BO3)3 as a function of the Gd molar concentration X are presented together with the empirical index formula.
