Abstract:The FIR (E2 → T2)-like transitions in CaF2:Dy2+ have been observed with both a Fourier transform spectrometer and Submillimeter lasers at magnetic fields of up to 50 kG. Both the 1 → 6 and 2 → 6 transitions exhibit minima of transition energy vs magnetic field. The possibility of utilizing the 2 → 6 transition energy minimum in conjunction with an optically-pumped D2O laser to produce tunable FIR laser radiation is discussed.
