Which mechanism disrupts spectral purity after laser welding?

💡 Explanation

Stimulated Brillouin Scattering (SBS) affects coherence; the original beam generates an acoustic wave, scattering light with a frequency shift. The coherence degrades because the reflected beam interferes, therefore increased noise occurs, rather than through plasma effects under stable parameters.
