N2 - For the first time to our knowledge, a dressed spontaneous parametric four-wave mixing (SP-FWM) process and fluorescence (FL) signals in hot alkali atom vapor are demonstrated in both theory and experiment. First, by scanning pumping fields, Autler-Townes (AT) splitting in SP-FWM and two-photon suppression dip in FL are observed. Then, by scanning coupling fields, single-, double-, and triple-dressed effect on those signals is demonstrated, such as suppression and/or enhancement of SP-FWM signal and suppressed two-photon emission peak of FL. The interaction effect between dressing fields on SP-FWM and FL signals is also observed. Such investigations can find potential applications in multichannel narrowband long-distance communication.
