Abstract

Thermal expansion coefficients along three main crystallographic axes of Tm-doped YA1O₃ (Tm:YAP) single crystals were investigated in the temperature range of 30-1350°C, and the results showed that they are 11.9458, 5.0012 and 10.5439 x 10^-6 K^-1, respectively. Polarized absorption and fluorescence spectra of Tm:YAP crystals in a-c directions were measured. The absorption cross sections near 794 nm are 8.64, 9.22 and 6.80 x 10^-21 cm², respectively. According to the fluorescence spectra, the A-axis emission cross section at 1.86 is determined to be 4.33 x 10^-21 cm², larger than those along two other axes. The results above showed that the anisotropy effect of thermal and optical characteristics exists in Tm:YAP crystal and b orientation is the preferred one. The origin and peculiarities of anisotropy were investigated and discussed.
