Abstract: High quality single crystals of Tm,Ho:GdScO3 were grown using the Czochralski method. The transmittance spectra of (100), (010) and (001) planes of the crystal were measured at room temperature, and the absorption coefficient and absorption cross-section of the crystal were calculated. The transition intensity parameters Ωt for Tm3+ and Ho3+ co-doped crystal were fitted using the product of dopant concentration N and absorption oscillator intensity f was fitted as a parameter, and the spectral parameters such as spontaneous radiation transition probability, radiative lifetime and fluorescence branching ratio were also calculated. The results show that, the Tm, Ho: GdScO3 crystal has good luminescence performance, and the calculated spectral parameters provide data reference for the study of its laser output performance.

Key words: laser technique, Tm,Ho:GdScO3 crystal, spectral property, Judd-Ofelt theory
