<div style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
We had a synthetic diamond company adjacent to our campus that made thick crystals. I believe they just used a solid-state laser to cut them up. I don't think it was anything exotic in terms of wavelength. Somewhere in the IR, I think. </div>
