A real laser requires a 3 (or more) level system (see diagram) in order to maintain a population inversion. If the lasing medium is pumped from the ground state at an optical frequency of 614.33 THz up to an excited state, which then quickly decays to a meta-stable energy level that is 0.245 eV lower, to finally relax back to the ground state by emitting photons at a certain wavelength; calculate this wavelength, using the speed of light as 299792458 m/s and ignoring refractive indices. Provide your answers to the nearest nanometre.
