| The spectroscopic properties of trivalent dysprosium (Dy3+) doped LiNbO3 crystals have been investigated at various temperatures. Absorption, emission, excitation and lifetime measurements have been performed and discussed in the framework of Judd-Ofelt approach. The stimulated emission cross sections of the strongest transitions of Dy 3+ ion have been estimated. A stimulated emission has been demonstrated in the near infrared. |
