Olivine and YAG solid-state laser rods

Above: Olivine, the most common mineral in Earth's upper mantle, and YAG, a common solid-state laser rod. The colors result from incorporated transition and lanthanide metals. Although the origin of these two materials is strikingly different, my research has shown that the color causing elements are in both cases randomly distributed thought the material.
