Mid-infrared emission and quantitative analysis of energy transfer processes in Er3+ doped oxyfluogermanate glasses Academic Article uri icon

abstract

  • Oxyfluogermanate glasses with good thermal stability were prepared by melt-quenching method. The investigation of 2.7m fluorescence spectra and energy transfer mechanism was performed pumped by an 808nm laser diode. The 2.7m radiative transition probability and emission cross section are 32.62s1 and 12.881021 cm2, respectively. The energy transfer parameters between 4I11/2 and 4I13/2 levels were calculated by Inokuti-Hirayama and Yokota-Tanimoto's model to further elucidate 2.7m fluorescent behaviors. It is found that the energy transfer mechanism among Er3+ is mainly dominated by dipole-dipole interactions. Results indicate that the prepared oxyfluogermanate glass is a promising candidate for mid-infrared laser applications.
