Which term refers to the maximum intensity location in the beam?

Explanation:
The main idea is about where the beam is brightest in space. The spot with the highest value of intensity across the beam’s cross-section is called the spatial peak intensity, Isp. It tells you exactly where energy density is greatest, usually at the focus. The spatial average intensity, Isa, would spread that brightness over the whole cross-section and lose information about the hotspot. The pulse average intensity, Ipa, concerns averaging over time within a pulse, not over space. The term temporal refers to time in general, not to a spatial location. So the term for the maximum intensity location in the beam is spatial peak intensity, Isp.
