- How many watts of <500nm light can 1 square centimeter of gold foil absorb? Is there a limit?

I have a LED light, which has a strong spectral peak around 470nm, and a broad emission spectrum in the deep red and infrared. I want to block most of the blue peak, and gold will absorb around 62% of this blue light. Will a polished gold foil surface of 1 cm2 be able to absorb 1 watt of this light?

And out of curiosity; is there a limit to this? Will it be able to absorb 100 watts of this light? Thanks!
