Perovskite Laser Rods, Vintage Soviet YAP Crystals rough from tattoo removal to cutting

from tattoo removal to cutting edge physics research

These are the first two gems cut in my new 'GemmoLantern' Design

Fortunately for us these uses require very exacting standards and sometimes crystals are rejected

following the movement of the sapphire melt during crysatllization

While material of this color would be called 'pink sapphire' in a gemological context

Perovskite Laser Rods, Vintage Soviet YAP Crystals rough from tattoo removal to cuttingThese are partial and complete laser rods of yttrium aluminum perovskite (YAP). As far as we know these are offcuts and failed rods that didn't quite make it into final production or usage. These laser rods were meant for use in solid state lasers. They would have had light pumped into them from the side, either by a lamp or by another laser, absorbed that energy and converted it into the powerful coherent beam that lasers are known for. Perovskite is
