摘 要：<正>A femtosecond laser with 800 nm,250 kHz and 150 fs was used to irradiate Sm3+-doped Li2O- Nb2O5-SiO2 glass.At the initial stage of the laser irradiation,a white emission was observed near the focal point of the laser beam inside the glass.After 20 second irradiation,a red and blue emission began to emerge.From the micro-Raman spectra,we found that the crystal spot has formed at the focal point of the femtosecond laser beam in the glass.The mechanism of the observed phenomena is discussed.
