Growth, crystal structure and optical study of Tm:LuYSiO5 single crystal

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 × 10−20 cm2. The full width half maximum is 8 nm at 791 nm. The larger emission cross-section of 0.27 × 10−20 cm2 at 1832 nm and broader full width half maximum of 277 nm make Tm:LuYSiO5 suitable for laser output around the 2.0 μm wavelength. The fluorescence decay time of the 3F4–3H6 transition was measured to be 1.44 ms. All the results indicate that Tm:LuYSiO5 should have potential technological applications in 2 μm tunable laser.
