摘　　要：In this paper the generation of four-wave mixing （FWM） signal using a noncycling transition of caesium atoms is investigated when the pumping laser is locked to the transition 6S1/2F= 4→6P3/2^F1 = 4, and meanwhile the probe frequency is scanned across the 6S1/2F = 4→6P3/2 transition. The efficiency of the four-wave mixing signal as a function of the intensity of the pumping beams and the detuning of the pumping beams is also studied. In order to increase the detection efficiency, a repumping laser which is resonant with 6S1/2F = 3→6P3/2F′= 4 transition is used. A theoretical model is also introduced, and the theoretical results are in qualitative agreement with experimental ones.In this paper the generation of four-wave mixing （FWM） signal using a noncycling transition of caesium atoms is investigated when the pumping laser is locked to the transition 6S1/2F= 4→6P3/2^F1 = 4, and meanwhile the probe frequency is scanned across the 6S1/2F = 4→6P3/2 transition.
