← ScienceWhich outcome occurs when intense laser pulses induce currents?
A)Terahertz radiation becomes strongly amplified✓
B)Crystal lattice destabilization accelerates
C)Plasma emission linewidth decreases
D)Optical absorption coefficient reaches minimum
💡 Explanation
Intense laser pulses induce currents, and therefore terahertz radiation amplifies because the transient currents radiate at these frequencies involving dipole oscillation mechanism. This radiation is amplified rather than emission quenching because dipole coherence leads to phase matching effects.
