Abstract
The crystal growth, structure, absorption spectra, J–O parameters, emission spectra, Gain spectra and fluorescence lifetime of Tm:LuYSiO5 single crystal were discussed for the first time to my best knowledge. The absorption cross-section is 0.91×10−20cm2. The full width half maximum is 8nm at 791nm. The larger emission cross-section of 0.27×10−20cm2 at 1832nm and broader full width half maximum of 277nm make Tm:LuYSiO5 suitable for laser output around the 2.0μm wavelength. The fluorescence decay time of the 3F4–3H6 transition was measured to be 1.44ms. All the results indicate that Tm:LuYSiO5 should have potential technological applications in 2μm tunable laser.
