Excited-State Absorption and Upconversion Pumping of Monoclinic Tm:KLu(WO4)2 Crystals

Abstract

Excited-state absorption of Tm 3+ ions ( 3 F 4 → 3 F 2,3 and 3 H 4 ) in the KLu(WO 4 ) 2 crystal is studied. Mid-infrared laser operation ( 3 H 4 → 3 H 5 ) is achieved with this crystal under upconversion pumping at 1.06 μm yielding 433 mW at 2291 nm. © 2022 The Author(s)
