Laser results are summarized for the low-phonon hosts KPb{sub 2}Cl{sub 5} and CaGa{sub 2}S{sub 4}. Radiative quantum efficiencies were determined in KPb{sub 2}Cl{sub 5}:Dy{sup 3+} directly from emission spectra in order to accurately determine its long-wavelength potential. The results indicate that room-temperature laser action should be possible to near 9 {micro}m in this host
