Energy transfer upconversion
text:
Energy Transfer Upconversion or ETU is a physical principle that involves the excitation of a laser-active ion to a level above that which would be achieved by simple absorption of a pump photon, the required additional energy being transferred from another laser-active ion undergoing nonradiative deexcitation. ETU involves two fundamental ideas: energy transfer and upconversion. The analysis below will discuss ETU in the context of an optically pumped [see optical pumping] solid-state laser. A
