Which risk increases when a high-powered laser engraver's focusing lens is severely scratched?

💡 Explanation

Increased plasma formation events occur because lens scratching causes non-uniform energy density creating localized thermal runaway initiating dielectric breakdown in the air. Therefore, plasma risk increases, rather than enhanced finish because beam quality degrades.
