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.

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?作者: lhz2009 时间: 2009-4-11 09:49
磁场一般加0.8-1T,呵呵与晶体尺寸有关系作者: xiulianqian 时间: 2011-8-23 10:31 我也做晶体的,需要者科联系0591-88023630陈小姐作者: landary 时间: 2011-8-25 20:33 作者: andycu 时间: 2011-8-28 10:54 作者: cuchu 时间: 2011-9-21 15:41 本帖最后由 cuchu 于 2012-5-30 09:25 编辑
