Which option is not a characteristic of IPL?

Explanation:
IPL uses broad-spectrum, non-coherent light. Coherence refers to light waves staying in a fixed phase relationship, which lasers produce. IPL, on the other hand, comes from a broadband lamp with filters, delivering many wavelengths at once without a stable phase relationship. So it is not coherent light, making that option the one that doesn’t fit. The other descriptors align with IPL: it is full-spectrum (or broadband) light, and the light is non-coherent.
