Abstract

The spectra of Eu³⁺-doped Y₂SiO₅ crystal were detected. The Judd-Ofelt intensity parameters Omega₂, Omega₄ and Omega₆ were calculated according to the absorption spectra, and were equal to 4.36 times 10 ^-20 cm², 0.74 times 10^-20 cm² and 1.074 times 10^-20 cm ², respectively. Persistent spectral hole burning (PSHB) were also observed at the temperature of 4.2K in the crystal. For 15mW dye laser (wavelength: 579.62nm ) burning the crystal immerged in liquid helium for 1 second a spectral hole with about 10MHz hole width were detected and the hole can keep for larger than 24 hours
