ABSTRACT
We report on the cascade continuous-wave operation of a diode-pumped TmYVO4 laser on the 3F4 â 3H6 (at â¼2â
µm) and 3H4 â 3H5 (at â¼2.3â
µm) Tm3+ transitions. Pumped with a fiber-coupled spatially multimode 794â
nm AlGaAs laser diode, the 1.5 at.% TmYVO4 laser yielded a maximum total output power of 6.09 W with a slope efficiency of 35.7% out of which the 3H4 â 3H5 laser emission corresponded to 1.15 W at 2291-2295 and 2362-2371â
nm with a slope efficiency of 7.9% and a laser threshold of 6.25 W.
