BY using an Ar+ion laser,a tunable Rh 6 G dye laser(linewidth 0.5 cm-1)pumped by the second harmonic of a YAG:Nd laser and a Coherent 899-21 dye laser as light sources and using a monochromator,a phase-locking amplifier and a computer as the data detecting system,we detect the optical properties of Eu3+-doped Y2SiO5 crystal.Persistent spectral hole buing(PSHB)are observed in the Eu3+ions spectral lines(5D0-7F0 transition)in the crystal at the temperature of 16K.For 15mW dye laser buing the crystal for 0.1s spectral holes with hole width about 80MHz both at 579.62nm and at 579.82nm are detected and the boles can remain for a long time,more than 10h.
