Cascade lasing at ∼2 μm and ∼2.3 μm in a diode-pumped Tm:YVO 4 laser

We report on the cascade continuous-wave operation of a diode-pumped Tm:YVO laser on the F → H (at ∼2 μm) and H → H (at ∼2.3 μm) Tm transitions. Pumped with a fiber-coupled spatially multimode 794 nm AlGaAs laser diode, the 1.5 at.% Tm:YVO laser yielded a maximum total output power of 6.09 W with a...

Zusammenfassung:	We report on the cascade continuous-wave operation of a diode-pumped Tm:YVO laser on the F → H (at ∼2 μm) and H → H (at ∼2.3 μm) Tm transitions. Pumped with a fiber-coupled spatially multimode 794 nm AlGaAs laser diode, the 1.5 at.% Tm:YVO laser yielded a maximum total output power of 6.09 W with a slope efficiency of 35.7% out of which the H → H laser emission corresponded to 1.15 W at 2291-2295 and 2362-2371 nm with a slope efficiency of 7.9% and a laser threshold of 6.25 W.
