Abstract: The dynamics of wave packets in an active fibre with saturable inertial nonlinearity of logarithmic type is considered. The possibility of forming spatially localised Gaussian wave packets (TEM₀₀ mode) with a large (significantly exceeding 100 μm²) mode area and a large (above 1 TW) peak power in such structures is shown.

Keywords: active fibre, saturable logarithmic nonlinearity, threedimensional soliton-like pulse, single-mode wave packet with giant peak power.
