← ScienceWhich risk escalates when a pulsed laser, exceeding material's damage threshold, strikes a conductive target?
A)Increased electromagnetic pulse emission✓
B)Reduced thermal stress fracturing
C)Enhanced dielectric breakdown strength
D)Diminished surface plasmon resonance
💡 Explanation
Increased electromagnetic pulse (EMP) emission escalates because rapid material ionization via the photoelectric effect releases accelerated charged particles, thus generating intense transient electromagnetic fields rather than thermal fracturing, therefore the risk increase from EMP not other thermal impacts.
