← ScienceWhich mechanism impairs laser ignition of an engine?
A)Plasma shielding reduces energy deposition✓
B)Raman scattering increases fuel preheating
C)Two-photon absorption increases combustion rate
D)Brillouin scattering compresses fuel droplets
💡 Explanation
Plasma shielding limits successful laser ignition due to the formation of a dense plasma that absorbs and reflects the laser energy diffusing outwards rather than generating effective ignition because other options do not block propagation.
