This inquiry has to do with Laserman121's fun little experiment found here.
I'm hoping there are some rock/crystal hounds that can help me duplicate his results. Last night a borrowed a friends nice fat chunk of calcite and lased a 1W 445nm through it for about 5 seconds and then turned it and the lights in the room off but the beam trail did not remain. After speaking to Laserman121 he told me not all calcite will do this but wasn't sure what type of calcite is needed to make this happen. Does anyone know anymore information or name of the calcite type I need to duplicate his results?
cheers
