We describe the spectroscopic measurements of Yb^3:LiYF_4 crystal at room temperature. The absorption and the emission spectra are measured with a 40.5 at% Yb^<3+> doped crystal. A maximum absorption coefficient of 42 cm^<-1> for the π polarization is measured at 960 nm with a spectral fullwidth of 12 nm. The upper-state (^2F_<5/2>) lifetime is measured to be 2.0 ms. The emission cross section at an oscillation wavelength of 1018 nm for the π and the σ polarizations are measured to be 5.3×10^<-21> cm^2 and 4.7×10^<-21> cm^2, respectively. The ground-state absorption coefficient at 1018 nm for the π and the σ polarizations are measured to be 4.0 cm^<-1> and 1.6 cm^<-1>, respectively.
