Abstract

We have grown ${\mathrm{LaCa}}_4\mathrm{O}{\left({\mathrm{BO}}_3\right)}_3$ (LaCOB), an isostructural member of ${\mathrm{GdCa}}_4\mathrm{O}{\left({\mathrm{BO}}_3\right)}_3$ (GdCOB) family and characterized its nonlinear optical properties. At 1064 nm, $d_{\mathrm{eff}}$ of $0.52\pm 0.05 \mathrm{pm}/\mathrm{V}$ and an angular sensitivity of $1224\pm 184 {\left(\mathrm{cm\; rad}\right)}^{-1}$ for type I frequency doubling in LaCOB were determined relative to those of ${\mathrm{KTiOPO}}_4$, $\beta ‐{\mathrm{BaB}}_2{\mathrm{O}}_4$, ${\mathrm{KD}}_2{\mathrm{PO}}_4$, ${\mathrm{LiB}}_3{\mathrm{O}}_5$, ${\mathrm{YCa}}_4\mathrm{O}{\left({\mathrm{BO}}_3\right)}_3$ (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 $\left|0.26\pm 0.04\right|\mathrm{pm}/\mathrm{V}$ and $\left|1.69\pm 0.17\right|\mathrm{pm}/\mathrm{V}$, respectively. From phase-matching angle measurements at 1064 and 1047 nm, we predict that LaCOB is noncritically phase matched at $1042\pm 1.5 \mathrm{nm}$.
