Yb3+ is a good candidate as a pump source because there are only two manifolds in the Yb3+ energy level scheme, the 2F7/2 ground state and the 2F5/2 excited state, and thus concentration quenching and excited-state absorption should not affect the lasing or the excitation wavelength [1]. Extensive investigations have been of Yb3+-doped glasses, fibers, and crystals [2, 3, 4, 5]. The relatively long fluorescence lifetime, as well as the broad absorption and emission bands, is more prominent for Yb-doped glasses than for crystals, making the glasses attractive for diode-pumped generation of ultra-short pulses, high-power ultra-short pulse amplification and tunable laser sources [6]. In addition, the ability to achieve high concentrations of Yb3+ ions and low loss also triggered the rapid development of various Yb3+-doped glasses such as phosphate, borate, and silicate glasses. However, up to now, there are few systematic investigations of the optical properties of Yb3+-doped germanate...
