Hello, I am new to the forum, so apologies If I am posting this thread in the wrong subforum. I was reading an article about laser-excited phosphor lighting, and how laser beam dumps are implemented to ensure only white light leaves the assembly. (Image attached) I also noticed that the assembly was only 7mm by 7mm! That is incredibly small! How are they even able to fit in a laser beam dump and how are they even built that small?
