Broad near‐infrared fluorescence properties of Nd‐doped PbClF crystals

Nd-doped PbClF crystals were grown with modified Bridgman method. Broad and flat emission band at 1.0 μm was observed. The FWHM value of 0.0091 wt.% Nd3+-doped PbClF crystal at 1064 nm reached up to 30 nm with the peak emission cross-section of 1.05×10-19 cm2. All the results indicated that Nd-doped PbClF crystal should be a promising tunable and ultrafast laser material. (© 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
