Recently, laser activity has been achieved in the low-phonon-energy, moisture-resistant bromide host crystals: neodymium-doped potassium lead bromide (Nd3+:KPb2Br5) and rubidium lead bromide (Nd3+:RbPb2Br5). Laser activity at 1.07 µm was observed for both crystalline materials. Laser operation at the new wavelengths of 1.18 and 0.97 µm resulting from the 4F5/2+ 2H9/2? 4IJtransitions (J=13/2 and 11/2) in Nd:RbPb2Br5 was achieved for the first time in a solid-state laser material. We present cw pump-probe spectra and discuss excited-state absorption and reabsorption processes due to the long-lived lower laser levels, as well as possible depopulation mechanisms feasible for more efficient laser operation in these crystals. The bromides are compared with potassium lead chloride (Nd3+:KPb2Cl5).
