| Abstract: | Large (up to 45mm in diameter and 50mm in length) ReCa4O(BO3)3 (ReCOB) and Nd:ReCOB (Re=Y or Gd) crystals with high optical quality were grown by well designed procedures. Crystal orientation was carefully determined. Based on the measurements of refractive indices the phase matching (PM) figures for both crystals were calculated. Theoretical calculation of the spatial distribution of the effective nonlinear coefficients, which show an asymmetric feature, was carried out to determine the optimal PM orientations which were experimentally confirmed, i.e. (66.3°, 134.4°) and (64.5°, 33.5°) for GdCOB and YCOB respectively. |
