We present an all-optical periodic pump–probe method for resonant excitation of coherent magnons in the magnetically ordered semiconductor CrS(Br,I). Temporal shaping of the pump pulse train, with repetition rates matched to magnon resonances, enables frequency-selective amplification, filtering, and addressing of specific modes and layers.
