Weird Yb:YAG Garnet Facet Rough, Experiment Gone Wrong crystal but these glass laser rodsThis is facet rough of weird mutated Yb: YAG. We tried to have it grown, it usually comes out a vivid blue green, but this one went wrong in the process. It has a combination of browns, yellows, greens, and occasional blue, giving more of a pondwater set of colors instead of the typical deep aqua blue you get from Yb: YAG. Since this was done by accident we don't know if we'll have more, but the colors are neat!
