Abstract
The energy transfer from Tm3+ to Nd3+ was explored in Tm,Nd:KPb_2Cl_5 for sensitization of a possible 5 µm Nd laser. Evidence for an efficient energy transfer from Tm3+ to Nd3+ under 785 nm excitation was obtained through monitoring changes in (i) the Tm^3+ decay behavior and (ii) the 5 µm emission intensity arising from the 4I_11/2-->4I_9/24 transition of Nd3+ ions. The quantum efficiency of the 5 µm emission from Nd3+ was estimated to be approximately four times greater in Tm,Nd:KPb_2Cl_5 compared with Nd:KPb2Cl5. Sensitization of Nd3+ with Tm3+ in KPb_2Cl_5 promises a significant increase in the maximum achievable slope efficiency of a potential 5 µm Nd laser.
