The longest reported lifetime for the Pr3+:1G4 energy level was measured at 2.46 ms in Cs:Ga:S:Cl2 glass, with a 24% total quantum efficiency. The Pr3+:1G4-3H5 emission, peaking at 1312 nm, is centred in the second optical telecommunication window, and the gain per unit pump power is predicted to be twice higher that of other candidates.
