In order to simplify manufacturing, stocking, and ordering, a number of standard sizes and orientations have been defined. If the size and orientation that you want is not listed here, please send a Request For Quotation to us!

Different orientations, crystallographically speaking, refer to the angles between the beam propagation direction and the crystallographic direction of the optic axis.

For Type I orientations, the polarization directions of the two longest wavelengths in the mixing process are in the same direction; the shortest wavelength in the mixing process has an orthogonal polarization direction.

...

For Type II orientations, the polarization directions of the two longest wavelengths in the mixing process are orthogonal to one another; the shortest wavelength in the mixing process, for the crystals listed here, has a polarization direction aligned to the polarization direction of the longest wavelength.

Examples of tuning applications are given for each crystal cut; other applications are possible.
