摘要：
Yb-doped PbClF crystals were obtained by a modified Bridgman method. Broadband emission (FWHM = 58 nm) with long lifetime (5.33 ms) was observed in 2.0% Yb3+-doped PbClF crystals. The Stark splitting of Yb3 + 2F7/2 level was calculated to be 801 cm(-1) in 0.5% Yb3+-doped PbClF crystals, and the corresponding population of lower laser level is about 2.13%. All the results indicated that Yb-doped PbClF crystals should be a promising material to ultrashort pulses output at 1.0 mu m. (C) 2012 Published by Elsevier B.V.
