Non-resonant fluorescence line narrowing (FLN) is used to examine resonances between excited states of ions. We discuss resonances between crystal field states in ruby, alexandrite and LaF3 : Pr3+ and between Zeeman sublevels in LaF3 : Er3+. We show that the latter is equivalent to excited state ESR, over which it can have many advantages.

A quantum computer is a computation device operated by means of quantum mechanical phenomena. There are many candidates that are being pursued for physically implementing the quantum computer.The quantum logical gate based on the electron spin resonance (ESR) was studied in ref. [3]. In this paper, we discuss a construction of Controlled-Controlled-NOT (CCNOT) gate by using the nonrelativistic formulation of ESR.
