Tunable mid-infrared luminescence from Er3+ -doped germanate glass. uri icon

abstract

  • Er(3+) -doped germanate glasses with superior thermal stability were prepared. Judd-Ofelt intensity parameters and important spectroscopic properties were discussed in detail. Upon 800 nm and 980 nm LD pumping, 2.7 m fluorescence characteristics were investigated and it was found that the effective 2.7 m emission bandwidth can reach to 101.79 nm in prepared glasses. The tunability of the 2.7 m emission band can be realized by adjusting the Er(3+) content. Moreover, a high-emission cross-section (11.09 10(-21) cm(2) ), large gain bandwidth (772.30 10(-28) cm(3) ) and gain coefficient (6.72 cm(-1) ) were obtained in the prepared sample. Hence, Er(3+) -doped germanate glass might be a promising mid-infrared material for tunable amplifiers or lasers.
