Thick Crystal Quartz 90 degree polarization rotator form CVI for YLF 1053nm, 1064nm
I have two for sale. This one is sealed never opened. Pictures of optic are the opened one. See my other sales for the opened box one.From catalog...
These rotators have the outstanding feature that their alignment is not a function of their rotation.They are simply placed in the beam at normal incidence.
Crystalline quartz rotators are very convenient high damage threshold devices.They are useful over a narrow band of wavelengths centered at the design wavelength.A 90 degree rotator centered at 500nm gives acceptable performance from 488-515nm in laser pumping schemes.
(So this one centered at 1053nm would be good for between 1038-1068nm.)CVI sells the 1" version for $785.00, This 2" version is not in any catalogs and is custom.So this one probably sold for $1,200-1,500. Substrate: Crystal Quartzsurface quality: < 0.5 arc secondsAR < 0.25%R per surfaceDamage threshold 10J/cm2, 20ns, 20Hz, 1MW/cm2, CW at 1064nm
