← ScienceWhich consequence results from limited temporal coherence in laser-induced breakdown spectroscopy?
A)Reduced plasma plume emission intensity✓
B)Increased spectral line broadening effect
C)Enhanced signal-to-noise measurement precision
D)Improved material ablation zone uniformity
💡 Explanation
Reduced temporal coherence means the laser's bandwidth increases, reducing the energy density at a specific frequency. This reduces plasma plume emission intensity because less energy is available for atomic excitation. Therefore, intensity decreases rather than improving ablation or precision.
