Effective sensitization of Dy3+:6H11/2 energy level by Tm3+ ions in KPb2Br5 crystal for 4.3 µm lasers
Listed in ScienceDB
To the best of our knowledge, this is the first study to investigate the use of Tm3+ to sensitize the Dy3+ ion and enhance the ∼4.3 µm emission from Dy3+:6H11/2 → 6H13/2 in the KPb2Br5 (KPB) crystal.
Description
The ∼4.3 µm fluorescence emission properties and energy transfer mechanism of the Dy:KPB and Tm,Dy:KPB crystals were examined. The results show that Tm3+ is an excellent sensitizer to the Dy3+ ion and can provide an efficient excitation channel; thus, the Tm,Dy:KPB crystal can be pumped by a commercial 808 nm laser diode (LD).
Compared with the Dy:KPB crystal, co-doping with the Tm3+ ion improves the absorption around 800 nm by an order of magnitude, and the energy transfer efficiency from Tm3+:3F4 to Dy3+:6H11/2 is as high as 76.7%, indicating that the Tm,Dy:KPB crystal has great potential application in ∼4.3 µm mid-infrared lasers under a commercial LD pump
