so this is a result of spontaneous parametric down-conversion right? so the BRIGHT LIGHT - those are quantum entangled photos??!! i so want a barium borate crystal ring!

Erm, isn't it a (frequency) up-conversion? So the green is definitely a frequency doubling from the infrared. And it's of course parametric. And I sure it's not stimulated, but is it then spontaneous?
From my point of view the decisive question is: Where does the bluish light come from?
