Abstract: The output power saturation effect in Yb – Er fibre lasers is experimentally observed. A formula for estimating the saturation power is derived. A method is proposed for measuring the ⁴I_11/2 level lifetime or the concentration of Er ions based on the measurements of the saturation power.

Keywords: fibre lasers, Yb – Er active medium, saturation power, excited state lifetime.
