Abstract
We report the observation of green fluorescence from Er3+ doped Ge silica optical fibre pumped by a CW Titanium - Sapphire laser in the 840-975 nm range. This emission is due to the multiphoton absorption and is attributed to the (2H11/2 + 4S3/2) decay level. The evolution of this emission as a function of the wavelength excitation and the effect of power pump are discussed.
