ABSTRACT
A compact TmGdVO4 laser pumped by a 794â
nm laser diode generated 6.09â
W at 2.29â
µm (3H4 â 3H5 Tm3+ transition) with a high slope efficiency of 30.8% and linear laser polarization (π). The polarized spectroscopic properties of Tm3+ in GdVO4 were also revised. The peak stimulated-emission cross section of Tm3+ is 2.97 × 10-20 cm2 at 2280â
nm, corresponding to an emission bandwidth of 42â
nm for π-polarized light.
