| 摘 要： | 综合分析了铬钙离子共掺钇铝石榴石晶体可见光－近红外区的室温吸收光谱，其中四配位和六配位的四价Ｃｒ＾２＋离子光谱成分是共存的，拟合得到的晶场参数符合光谱学的理论和实验规律，并且这两类Ｃｒ＾４＋中心的晶声性质均受到晶体中二价补偿离子Ｃａ＾２＋的影响。 |
| 关 键 词： | YAG晶体 晶场特性 吸收光谱 铬钙离子 共掺 |

| Abstract: | High quality optical crystal of Cr, Ca:YAG was grown by Czochralski method and annealed in an oxidization atmosphere successfully in our laboratory. VIS-NIR absorption spectra, crystal-field parameters and characteristics of Cr4+ centres in the crystal, which are influenced by divalent compensation Ca2+ ion, are determined and analyzed in detail. Some evidences suggest that a reasonable doping concentration would be favourable to emitting tunable laser from such a laser crystal. |
| Keywords: | intracavety frequency doubling mode locked laser unstable resonator KTP crystal. |
