Abstract

A 6.4at.% Tm3+-doped BaGd2(MoO4)4 cleavage crystal was grown by the Czochralski method. Detailed spectral properties of this crystal were investigated, including the polarized absorption and emission spectra and the fluorescence decay. The maximum absorption cross section of the pump band is 3.5cm×1020cm at 798nm with a bandwidth of 8nm, which means that this crystal is suitable for laser diode pumping. The Judd–Ofelt theory was used to calculate the radiative transition probabilities between multiplets. Pumped by a Ti:sapphire laser, the 2.0μm quasi-cw laser operation was performed using a cleaved 1.1mm thick wafer of this crystal in a hemispherical cavity. The achieved highest slope efficiency was 51% with a 6.7% output coupler and the corresponding threshold was 31mW. The results show that a Tm3+:BaGd2(MoO4)4 crystal is a promising candidate for 2.0μm microchip lasers.
