| Abstract: |
Although well known for its near infrared emission, Nd:YLF is far less studied in the mid-infrared range (MIR). In this work, the polarized stimulated emission cross section of the decay to the 4I 15/2 , at around 2 μm and the branching ratios of all the radiative decay channels from 4F 3/2 to the lower levels, have been estimated by applying the beta-tau method. Moreover, the absorption of Nd:YLF crystal has been measured from the near infrared up to the crystal absorption edge of the spectrum in MIR. Finally, the emission from the first excited state to the sublevels of the ground state in mid infrared at around 4.9 and 5.9 μm have been observed and discussed. • The contribution of the ^4F3/2 to ^4I15/2 decay in Nd:YLF is about 0.5%. • FTIR measurements presented here agree with grating spectrometry from literature. • All transitions in the absorption and emission mid-IR have been identified.
