Description/Abstract

This paper presents experimental results on the mid-infrared emission of rare-earth doped gallium lanthanum sulphide glasses and fibres. Measured fluorescence includes the 3.4 µm transition (1G4 to 3F4) in Pr3+-doped Ga:La:S fibre, the 3.6 µm transition (4F(9/2) to 4I(9/2)) in Er3+- doped Ga:La:S fibre, and the 4.3 µm transition ( 6H(11/2) to 6H(13/2) ) in Dy3+-doped Ga:La:S bulk glass. Fibre lasers with these emission wavelengths would be of interest for gas sensing applications.
