Abstract We have measured the lifetimes of the 2.8 {mu}m emission band for Er{sup 3+}- and Ho{sup 3+}-doped fluorides including LiYF{sub 4}, BaY{sub 2}F{sub 8}, LaF{sub 3}, and KY{sub 3}F{sub 10}, and for numerous oxides such as Y{sub 3}Al{sub 5}O{sub 12}, YAlO{sub 3}, La{sub 2}Be{sub 2}O{sub 5}, and other crystals. Several quantum yields and branching ratios were experimentally evaluated as well, in order to determine the radiative lifetime of the upper laser level for the 2.8 {mu}m transition. This information was employed to assess the cross sections of the 2.8 {mu}m infrared emission band for several of these crystals, which involves the {sup 4}{ital I}{sub 11/2}{r_arrow}{sup 4}{ital I}{sub 13/2} transition for Er, and the {sup 5}{ital I}{sub 6}{r_arrow}{sup 5}{ital I}{sub 7} for Ho.
