How do Potassium Titanyle Phosphate crystals double the energy of photons?
It confuses me when i think about it in its simplest form =
a single 1.16ev (1064nm) photon enters the crystal.
a single 2.33ev (532nm) photon exits the crystal.
How did that photon change to a higher energy state??
Is the photon that exits still the same photon that entered?
Does the higher energy photon posses any net gain in power?
Or is there wasted energy in the process?
Thank you for helping me understand this.
