[摘要]：Growth, spectroscopic properties, and laser performance of Yb, Na:PbF2 crystals have been investigated. With a 2 mol.% Yb3+-doped sample we obtained 2.65W output power at 1045 nm for 7.5W of incident power at 976 nm. The laser wavelength could be tuned from 1017 to 1078 nm, showing the great potential of Yb, Na: PbF2 as an amplifier medium for femtosecond pulses. (C) 2011 Optical Society of America
