Which risk escalates when focusing a high powered laser?

💡 Explanation

Air plasma formation increases because the mechanism of multiphoton ionization is dramatically enhanced at the focal point where irradiance is highest; therefore plasma readily forms rather than other scattering processes because the electric field peaks intensely.
