Perovskite Laser Rods, Vintage Soviet YAP Crystals rough These are the first two

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

This is rutile

from tattoo removal to cutting edge physics research

and the dichroic nature should make it incredible when rolled

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

Perovskite Laser Rods, Vintage Soviet YAP Crystals rough These are the first twoThese 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
