If you hold two pieces of quartz glass side by side, you cannot tell them apart.Same color. Same clarity. Same chemical formula: SiO₂.But shine a 193nm deep-UV laser through one of them, and it passes straight through. Shine the same laser through the other, and it's completely absorbed before it even reaches...
