Abstract

Studies of line intensity in the optical and magneto-optical spectra in the holmium-containing paramagnetic garnet Ho3+:YAG were carried out within the visible spectrum at T = 85 K. Detailed investigation of the magnetic circularly polarized luminescence spectra at 85 and 300 K on 5S2 → 5I8 emission transition in Ho3+:YAG was carried out. A quasi-doublet state in the energy spectrum of the Ho3+ ions was observed, characterized by a significant magneto-optical activity, which is caused by a large Zeeman splitting of the quasi-doublet. The measurement of the magnetic circular polarized luminescence spectrum carried out within one of the emission lines of the luminescence band 5S2 → 5I8 in Ho3+:YAG at 85 K shows significant magneto-optical effects of the intensity change of the emitted light, compared to that measured for the other emission lines in the same luminescent band.
