| 摘 要： | 在室温下测试了Nd:KYW(Nd:KY(WO4)2)、Nd:KGW(Nd:KG(WO4)2)晶体的吸收光谱,有相似性,这是由于结构相似.吸收峰位置稍有偏移,因为Nd3+离子进入晶体取代离子的半径不同,晶格对Nd3+跃迁影响大小不同.根据J-O理论计算的晶场强度参数反映了它们性质的炯异.同时测试的偏振吸收光谱,表明了明显的偏振性,不同的偏振有不同性质,同一偏振两晶体的性质存有差异.

| Abstract: | Absorption spectras of Nd:KYW and Nd:KGW crystal at room temperature were investigated.Although the structure of them are similar,there was a bit discrepancy between Nd:KYW and Nd:KGW of the set of spectra corresponding to the radius of Nd3 ,Y3 and Gd3 .According to the J-O theory,the osillator strength and intendity parameter were calculated and discussed.Meanwhile,polarization absorption spectra of them were given,which revealed the character of polarization obviously. |
