Er, Yb:Phosphate glass EAT14
Description
Er3+/Yb3+ co-doped phosphate glass — as the 1540nm eye-safe radiation sources pumped by LD which can emit eye-safe 1540nm laser radiation directly used in laser ranging finder and telecommunication communication.
Er3+ emission transition occurs within this wavelength range corresponding to the 4I13/2 →4I15/2 . However, Er3+ absorption itself is too weak to allow direct pumping and so, energy transfers are required. The most efficient ones are given by Yb3+ ions under absorption from the 2F7/2 → 2F5/2 transition, followed by energy transfer to the 4I11/2 Er3+ level and fast nonradiative transition to the Er3+ 4I13/2 level which emits the expected fluorescence.
Er,Yb:glass laser with radiation output at the wavelength of 1540 nm does not require the addition of additional components.
