Abstract: We demonstrate the seeded spontaneous parametric four-wave mixing (SP-FWM) process
associating with the fluorescence signals of Pr3+:YSO both theoretically and experimentally. For the
first time, the dressed SP-FWM processes are observed by self-dressing and/or external-dressing in this
crystal. Various possible amplification processes are discussed by selectively seeding various
multi-wave mixing (MWM) signals. Two contributions of the dressing effect and the dipole-dipole
interaction to the linewidths of SP-FWM signal and the conjugate signal of the seeding MWM signal
associating with fluorescence signal have been distinguished. In addition, the Autler-Townes-like (or
Autler-Townes) splitting effect of fluorescence spectrum induced by itself (or external) field and the
mutual interaction between two fluorescence signals are investigated which are well explained using
the presented theoretical model. Such results can find potential applications in all-optical
communication and optical information processing on photonic chip.
Key words: Nonlinear optics; seeded spontaneous parametric four-wave mixing; fluorescence signals

Atomic coherence is the result of interaction between light and materials, which leads to
many important physical phenomena. Currently, most experimental researches on atomic
coherence are reported in hot or cold atomic gas systems. Compared with atomic gases, atomic

coherence-induced effects in solid materials have more practical applications. The recent research
progresses related to atomic coherence in solid-state materials, including ically
