We report on the chaotic dynamics in a passively Q-switched 2.3-μm thulium laser operating on the 3H4 → 3H5 transition. The experiment exploits a Tm:LiYF4 crystal and various laser cavity configurations, involving an optional cascade laser on the

Upconversion pumping of thulium lasers emitting around 2.3 µm (the 3H4 → 3H5 transition) has recently attracted a lot of attention as it is compatible with the mature Yb-laser technology. To explore this possibility, we built a mid-infrared Tm:LiY

We report on the first laser operation of a disordered Tm:CaGdAlO4 crystal on the 3H4 → 3H5 transition. Under direct pumping at 0.79 µm, it generates 264 mW at 2.32 µm with a slope efficiency of 13.9% and 22.5% vs. incident and absorbed pump powe

We report on a bulk thulium laser operating on the 3H4 → 3H5 transition with pure upconversion pumping at 1064 nm by an ytterbium fiber laser (addressing the 3F4 → 3F2,3 excited-state absorption (ESA) transition of Tm3+ ions) generating 433 mW at

Excited-state absorption of Tm3+ ions (3F4→3F2,3 and 3H4) in the KLu(WO4)2 crystal is studied. Mid-infrared laser operation (3H4→3H5) is achieved with this crystal under upconversion pumping at 1.06 μm yielding 433 mW at 2291 nm. © 2022 The Aut

We present studies about upconversion pumping at 1.05 µm for Tm:YLF lasers emitting at 2.3 μm. To improve the performance of this pump, we explore the possibility dual pumping with 780 nm.

Cascade lasing in a Tm:CALGO crystal at 1.8 µm (3F4→3H6) and 2.3 μm (3H4→3H5) is demonstrated with the originality of lacking a competition between the two laser channels, owing to dual-wavelength (direct and upconversion) pumping.
