Very often it is necessary to separate a laser's harmonics from its fundamental wavelength, or to combine dissimilar wavelengths so that they will travel along the same optical path. These specialized functions are performed using engineered multi-layer coatings, resulting in optical elements called beam separators and beam combiners, respectively.
