Abstract: Yb-doped PbClF crystals were obtained by a modified Bridgman method. Broadband emission (FWHM=58nm) with long lifetime (5.33ms) was observed in 2.0% Yb3+-doped PbClF crystals. The Stark splitting of Yb3+ 2F7/2 level was calculated to be 801cm−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 1.0μm. [Copyright &y& Elsevier]
