Abstract
Persistent spectral hole burning is observed at room temperature in th e excitation spectrum for the F-7(0)-->D-5(0) transition of Sm2+ in KL aF4 single crystals, The hole width and depth are about 10 cm(-1) and 18% of the total intensity, respectively. it is concluded that the dom inant burning mechanism in this crystal is a photoionization of electr on trapping at a site other than Sm3+ ions because of the absence of a n antihole around the burned hole.
