This paper presents a method for the separation of excited-state absorption transitions from different initial levels by phase-sensitive detection by use of the double-modulation technique. This technique is also applicable for the distinction of spectrally overlapping transitions, and in connection with Judd–Ofelt calculations it allows the excited-state absorption cross sections to be determined. With this method, the  5I7(5S2, 5F4), 5I6(5G6, 5F1), 5I65F2, and  5I65F3 transitions in the spectral range between 720 and 860 nm in Ho3+-doped YLiF4 were measured and their cross sections determined. The method can be used for any similar system.
