Optical absorption measurements of Tm3+ in 5NaF.9YF3 crystal have been investigated. The Judd-Ofelt (J-O) theory was applied to the absorption spectra of Tm3+: 5NaF.9YF3 to obtain three JO parameters t=2,4,6. Values of the JO parameters were subsequently used to determine the radiative transition probabilities, the radiative lifetimes and the branching ratios. The calculated parameters show that Tm3+: 5NaF.9YF3 crystal possesses important spectroscopic and laser properties that are favorable for this material to become a potential candidate as an efficient laser system.} }
