Effect of Irradiation on YAG Crystals by Femtosecond Pulse Laser
A 120 fs femtosecond pulse laser with wavelength of 800 nm was applied to irradiate YAG crystals grown by Czochralski (CZ) and temperature gradient technique (TGT) methods. Absorption spectra and EPR have been measured. The results show that Fe 3+ ions have been changed to Fe 2+ ions in CZ grown YAG crystals and F + centers formed after irradiation. Anti-irradiation ability of YAG grown by TGT method is better than CZ sample.
