Abstract:

© 2015 AIP Publishing LLC. Oxyfluogermanate glasses with good thermal stability were prepared by melt-quenching method. The investigation of 2.7μm fluorescence spectra and energy transfer mechanism was performed pumped by an 808nm laser diode. The 2.7μm radiative transition probability and emission cross section are 32.62s-1 and 12.88×10-21 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 2.7μm 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.
