Abstract采用波长为800 nm,脉冲宽度为120 fs的飞秒激光对提拉法和温梯法生长的YAG晶体进行辐照。并对辐照后的样品进行吸收光谱及电子顺磁共振谱(EPR)的检测。结果表明,提拉法的晶体在经过辐照后,255 nm吸收峰减弱,同时在370 nm处产生新的宽峰吸收,其产生原因是由于样品内部分Fe~(3+)转化成Fe~(2+),并有少量F~+心生成。对比两种不同方法生长的晶体,温梯法生长的YAG晶体的抗激光辐照能力略优于提拉法生长的晶体。

Other AbstractA 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.
