Which risk increases in high-power laser cutting applications due to beam instability?

💡 Explanation

Elevated plasma formation likelihood increases, because hot spots caused by beam instability initiate rapid ionization of the surrounding air and vaporized material, driving avalanche ionization, therefore, a plasma forms rather than solely thermal ablation, distorting the laser focus.
