Abstract: A detailed study of thermo-optic properties of 1.5 at.\% Yb:Lu$_2$O$_3$ single crystal is performed. Thermo-optic dispersion formulas are derived for dn/dT coefficient and thermal coefficient of the optical path. At the wavelength of 1.03 μm, dn/dT = 5.8 × 10$^{−6}$ K$^{−1}$. High-precision temperature-dependent measurements of the thermal expansion coefficient α are performed. At the room temperature (RT), α = 5.880 ± 0.014 × 10$^{−6}$ K$^{−1}$. Temperature dependence of the bandgap is analyzed, yielding RT value of E$_{g}$ = 5.15 eV and dE $_{g}$/dT = –3.7 × 10$^{−4}$ eV/K. Sensitivity factor of the thermal lens is calculated for a diode-pumped Yb:Lu$_2$O$_3$ crystal versus the pump spot radius and crystal temperature.
