Abstract

Oscillation at 5.5 μ m wavelength has been investigated in the low-phonon, moisture-resistant RbPb 2 Cl 5 : Dy 3 + crystal in free-running mode at room temperature. In line with our knowledge this is the longest laser wavelength for a rare-earth doped crystal that does not require any special precautions for survival. Spectra and kinetics of luminescence of the new laser crystal were investigated under pumping to 1.3 μ m absorption band, corresponding to lasing experiments. Emission cross sections were determined for mid-IR transitions. It was found that emission cross section on the H 9 2 6 + F 11 2 6 H 11 2 6 laser transition at 5.5 μ m wavelength is as high as 0.6 × 10 20 cm 2 .
