This crystal can split light particles

A)  I love you more everytime I watch a new video, but....  I have a question,  so B) What happens if you entangle weak particles,  let's say a green or lower,  and then put one of them through the laser process to enhance it's energy?  Does the entangles particle gain energy?  If so,  doesn't that break the laws of thermodynamics(which I have always believed were fallible anyway)?
