Nd3+ and Er3+ ions are doubly doped in the core part of a single-mode silica fiber. By end-pumping with an Ar ion laser at 514 nm, multiwavelength laser oscillations at 0.908, 0.932, 1.08, and 1.552 μm have been successfully achieved in the 1.5-m-long fiber with an adsorbed pump power of 70 mW.

    In this article the author comments on confined propagation and near single-mode laser oscillation in a gain-guided index antiguided (GG + IAG) optical fiber. It states that it is named IAG fiber because the index of the core is lower than its cladding and infinite cladding boundary. It further...
