What is the intensity of light if its direction is returned back

[cindy 2005]

Question: Assume that using some "modern techniques" we can integrate the intensity of light from a light source by let light moves in a closed loop. Does intensity of light increase in terms of time t? If it does, what is the intensity of light in term of time t if its direction is controlled to move to the original direction and same plane? I use the term closed-loop meaning that light is reflected back to the same original direction and plane as where it comes from.

 

Thanks,

ps: I try to calculate the intensity of light when light moves in a closed loop, and I see that its intensity increases based on math. I also see that there is an hugh energy can be integrated if above assumption is practical.

Does intensity of light increase in terms of time t?

In principle, yes, although doing it would pose a few practicle problems.

 

It's not much different from filling a bottle, or similar things.
