We have grown LaCa4O (BO3)3 (LaCOB), an isostructural member of GdCa4O(BO3)3 (GdCOB) family and characterized its nonlinear optical properties. At 1064nm, deff of 0.52±0.05 pm /V and an angular sensitivity of 1224±184(cm rad)-1 for type I frequency doubling in LaCOB were determined relative to those of KTiOPO4 , β-BaB2O4 , KD2PO4 , LiB3O5 , YCa4O(BO3)3 (YCOB), and GdCOB. The dαββ and dγββ coefficients of the nonlinear optical tensor for LaCOB, GdCOB, and YCOB were determined to be equivalent within the experimental uncertainty and have values of ∣0.26±0.04∣pm/V and ∣1.69±0.17∣pm /V , respectively. From phase-matching angle measurements at 1064 and 1047nm, we predict that LaCOB is noncritically phase matched at 1042±1.5 nm .
