Relationship between light yield and excitation fluence was studied by changing laser intensity and the distance between focal spot and LSO crystal. Results show that nonlinear energy threshold of LSO crystal is about 3 J/cm3.

The polarized Raman spectra of Lu2SiO5 (LSO) and Gd2SiO5 (GSO) have been measured. The symmetries of the vibrational modes in the LSO and GSO Raman spectra were determined with using the group-theory calculations. Evaporation of SiO2 from the LSO cry
