AbstractThis work reports the sensitization of Ho3þ- doped fluoroindate glasses for near and mid-infrared emission. Special attention has been paid on the comparative analysis of the luminescent properties of the glasses co-doped with 0.8ErF3/1.6HoF3, 0.8YbF3/1.6HoF3, and 0.8TmF3/1.6HoF3. Moreover, the energy transfer processes be-tween rare-earth (donor-acceptor) ions in fluoroindate glasses pumped by and 980 nm or 796 nm laser diode have been examined. The most effective sensitization for 2 μm emission has been obtained in glass co-doped with Tm3þ/Ho3þ. In the MID-infrared spectral range (2.85 μm) glass co-doped with Yb3þ/Ho3þis characterized by 2.6 times higher intensity than co-doped with Er3þ/Ho3þ. However, in Er3þ/Ho3þ-co-doped glass broad emission at MID-IR region (FWHM ¼200 nm) has been obtained.
