We have grown LaCa4O(BO3)(3) (LaCOB), an isostructural member of GdCa4O(BO3)(3) (GdCOB) family and characterized its nonlinear optical properties. At 1064 nm, d(eff) 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, beta -BaB2O4, KD2PO4, LiB3O5, YCa4O(BO3)(3) (YCOB), and GdCOB. The d(alpha beta beta) and d(gamma beta beta) coefficients of the non-linear 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 1047 nm, we predict that LaCOB is noncritically phase matched at 1042 +/- 1.5 nm.
