The excited state absorption spectrum of Sm/sup 2 +/ in SrF/sub 2/ has been observed. The absorption peaks associated with the /sup 5/D/sub 0/(4f/sup 6/) excited state were found to be displaced by approximately 3000 cm/sup -1/ from the absorption bands arising from the /sup 7/F/sub 0/(4f/sup 6/) ground state (after taking the /sup 5/D/sub 0/-/sup 7/F/sub 0/ energy separation into account). The observed peak separation is ascribed to the 4f-5d exchange interaction. From the measured peak positions, the exchange energy for the Sm/sup 2 +/ impurity was determined to be about the same order of magnitude as expected for the free ion. The implications of the properties of the excited state absorption bands for the performance of the SrF/sub 2/:Sm/sup 2 +/ laser are considered. 15 refs., 2 figs.
