We report on the experimental measurement of the saturated gain of Yb3+:Sr5(PO4)3F at the 1047-nm laser line as a function of pump fluence and probe energy. The emission line was accurately modeled as a single homogeneous extraction, yielding values of 6.2 × 10–20 cm2 for the emission cross section and 3.3 J/cm2 for the saturation fluence.
