Yb:LiYF4 Crystals
A high-energy-storage Yb-doped material is one of the most promising materials for use in the next generation of diode-pumped high-power lasers. Diode pumping of this material is appropriate because of the material’s long emission lifetime (milliseconds) and strong absorption characteristics in the spectral range of available high-power laser diodes (900–1000 nm). 


The Yb-doped material has the highest quantum efficiency (>90%) among commercial laser materials. Yb:LiYF4 (Yb:YLF) have wider emission spectra than Yb:YAG, which is necessary for the generation and amplification of ultrashort pulses. A YLF host crystal has higher thermal conductivity than glass, resulting in negligible lower thermal lensing. The YLF crystal also has the capability of a high degree of doping with ytterbium ions.
