Abstract: The refractive index dispersion of the $\gamma$-BiB$_3$O$_6$ crystal in the wavelength range 0.43–0.81 $\mu$m has been measured. It has been shown that the principal refractive indices $n_1$, $n_2$, and $n_3$ are on average higher than those of $\alpha$-BiB$_3$O$_6$, but are slightly lower than those of $\delta$-BiB$_3$O$_6$. The temperature dependences of the rotation angle $\varphi(T)$ of the optical indicatrix and birefringence $\Delta n_2(T) = (n_1-n_3)(T)$ have been studied in the temperature range 100–963 K. It has been shown that the $\gamma$-BiB$_3$O$_6$ crystal is stable in this temperature region.
