| 简介 |
The object(s) of the invention is to provide a Faraday rotator, an optical isolator, and optical processing equipment, which has a transmittance higher than that of TGG, is capable of upsizing, and has a higher performance index in the visible wavelength region in general, and on wavelengths of up to 400 nm in particular.
The Faraday rotator is characterized by containing as a main component a fluoride represented by the following general formula (1) or (2) :
[in-line-formulae]RE1F3-x (1)[/in-line-formulae]
[in-line-formulae]LiRE2F4-x (2)[/in-line-formulae]
where 0≦x<0.1, and RE1 or RE2 is at least one element selected from the group of rare earth elements. |
