摘要：

The spectroscopic properties of GdAl3(BO3)(4):Tm3+ single crystal for the Tm3+ transition near 1.9 mu m are presented. The absorption cross section, the emission cross section, and the potential laser gain near 1.9 mu m are investigated for both sigma and pi polarizations. The broad absorption band at about 797 nm and high value of the above cross section are promising features for obtaining a laser diode pumped Tm3+ laser. The maximum emission cross sections are 1.29x10(-20) and 6.60x10(-20) cm(2) at 1.85 mu m for the sigma and pi polarizations, respectively. The potential laser gain curves indicate that more than 200 nm tunability range is expected for this material. (C) 2006 American Institute of Physics.
