Gratings with very high diffraction efficiencies, especially for polarized light are extremely suitable for laser applications such as; wavelength tuning and stabilization, beam splitting, laser pulse stretching and compression.
ZEISS provides optimized gratings for various applications in the spectral range from 0.2 µm to 12 µm. The absolute efficiency provided by a grating at the wavelength of the laser used is of special significance. To obtain a high level of efficiency, deliberate use is made of the dependence of the diffraction efficiency on the direction of polarization.
