← ScienceWhich outcome occurs when a pulsed laser focused through water experiences very high power densities?
A)Optical breakdown generates plasma formation✓
B)Stimulated Raman scattering linewidth narrows
C)Self-phase modulation increases beam divergence
D)Wavefront distortions decrease Kerr effect
💡 Explanation
Optical breakdown forms plasma due to strong electric fields removing electrons. This is ionization because focused laser light reaching the ionization threshold results in plasma; therefore, the answer is optical breakdown generating plasma, rather than subtle Raman or Kerr effects occurring at lower intensities.
