Which outcome occurs when a high-powered laser is focused on a transparent dielectric material, causing extremely localized heating?

💡 Explanation

Optical breakdown occurs because the intense electric field causes ionization, generating a plasma. This plasma absorbs more laser energy, leading to further ionization; therefore, optical breakdown results in a dense plasma, rather than graded fluorescence caused by lower intensities.
