本文报道了一种高质量的Cr,Nd:YAG晶体,其吸收波长为1.0 at. %的Cr 3Cr和1.1 at. % Nd ~(3+)单晶。光谱结果表明,Cr ~(3+)离子共掺杂有利于提高泵浦效率。在40 Hz、1.06 μm波长下,Cr,Nd:YAG晶体的最大平均功率为20.24 W,电光效率和斜率效率分别为3.00%和3.77%。同时,在Nd:YAG晶体上获得的最大平均功率仅为13.32 W,电光转换效率和斜率效率分别为1.97%和2.47%。此外,Cr,Nd:YAG晶体的光束质量与Nd:YAG晶体相当。因此,Cr,Nd:YAG晶体是一种比Nd:YAG晶体具有更高激光性能和更强抗辐射能力的有前途的激光晶体。因此,Cr,Nd:YAG晶体可应用于大功率系统和辐射环境中。
We present a high-quality Cr,Nd:YAG crystal with 1.0 at. % Cr3þ and 1.1 at. % Nd3þ grown successfully by the Czochralski method. Spectroscopy results indicate that codoped Cr3þ ions are advantageous for improving pumping efficiency. The maximum average power of 20.24 W operated at 40 Hz and 1.06 μm is obtained on the Cr,Nd:YAG crystal, with electrical-to-optical and slope efficiencies that correspond to 3.00% and 3.77%. Meanwhile, the maximum average power of only 13.32 W is obtained on the Nd:YAG crystal, with the electrical-to-optical and slope efficiencies of 1.97% and 2.47%, respectively. In addition, the laser beam quality of the Cr,Nd:YAG crystal is comparative with that of the Nd:YAG crystal. Therefore, the Cr,Nd:YAG is a promising laser crystal with higher laser performance and stronger radiation-resistant ability than the Nd:YAG crystal. Thus, the Cr,Nd:YAG crystal can be applied to high-power ystems and radiant environments.
