The objective of the present work is to investigate the thermo-optical (TO) properties of the relaxor-type ferroelectric sodium-bismuth titanate (SBT) single crystals as a function of temperature, using the thermal lens and optical second harmonic generation (SHG) techniques with the emphasis on the TO response near the phase transitions (PT). Symmetry-forbidden SHG signals above 538 K in the [00l] cut SBT crystal are detected. The signals are related to the coexistence of the tetragonal and rhombohedral phases. Heating of the uniaxial strain poled SBT crystal revealed remarkable changes of the TO signal near the successive PT.
