TGG晶体
请问谁有TGG晶体,哪家质量比较好? 这种晶体干什么用的,想了解一下。 铽镓石榴石晶体,一种常用的磁光晶体,用于做光隔(离器)。 TGG(Tb3Ga5O12,铽镓石榴石)用于制作法拉第旋光器/隔离器的磁光材料。TGG法拉第光旋转器和光隔离器广泛应用于各种激光系统中,如光纤激光器、掺饵光纤放大器,多级激光放大器,光参量振荡器,环行激光器,种子注入型激光器、永磁型的光旋转器等。 找CASTECH

有没有TGG晶体的厂商,把参数发来看看啊~
The magneto-optical crystal Terbium Gallium Garnet TGG is an optimum material for Faraday devices (Rotator and Isolator) in the range from 400 nm-1100 nm, excluding 470-500 nm. TGG has a combination of excellent properties such as large Verdet constant, low light loss, high thermal conductance and high light damage threshold which makes it a unique material for Faraday devices particularly suitable for YAG lasers and Ti: sapphire tunable lasers, ring lasers and seed injected lasers.

提供优质TGG晶体
:我公司专业生长和加工TGG晶体,欢迎垂询。电话13564631988;email:liuzp121@hotmail.com 其实晶体好买,可是你那个磁场怎么办?多大的磁场才能起到隔离的作用? 磁场一般加0.8-1T,呵呵与晶体尺寸有关系 {:6_143:}我也做晶体的,需要者科联系0591-88023630陈小姐
