What will happen if the inner walls of the perfect blackbody  (shown in the image) is made perfectly reflecting?

enter image description here

I am curious about making the inner walls of this blackbody perfectly reflecting instead of perfectly absorbing. 1.If I keep on giving in incident radiation,the photon density inside will increase,will it result in any interesting observation? 2.There will still be a non zero radiation escaping out through the inlet,so after giving in a large amount of radiation,will it work like a torch,with radiation escaping the closed system over time?

  1. If I keep on giving in incident radiation,the photon density inside will increase, will it result in any interesting observation?

  2. There will still be a non-zero radiation escaping out through the inlet,so after giving in a large amount of radiation,will it work like a torch, with radiation escaping the closed system over time?
