We have searched for axion-like resonance states by colliding optical photonsin a focused laser field (creation beam) by adding another laser field(inducing beam) for stimulation of the resonance decays, wherefrequency-converted signal photons can be created as a result of stimulatedphoton-photon scattering via exchanges of axion-like resonances. Aquasi-parallel collision system (QPS) in such a focused field allows access tothe sub-eV mass range of resonance particles. In past searches in QPS, forsimplicity, we interpreted the scattering rate based on an analyticallycalculable symmetric collision geometry in both incident angles and incidentenergies by partially implementing the asymmetric nature to meet the actualexperimental conditions. In this paper, we present new search results based ona complete parameterization including fully asymmetric collisional geometries.In particular, we combined a linearly polarized creation laser and a circularlypolarized inducing laser to match the new parameterization. A 0.10 mJ / 31 fsTi:sapphire laser pulse and a 0.20 mJ / 9 ns Nd:YAG laser pulse werespatiotemporally synchronized by sharing a common optical axis and focused intothe vacuum system. Under a condition in which atomic background processes werecompletely negligible, no significant scattering signal was observed at thevacuum pressure of $2.6 \times 10^{-5}$ Pa, thereby providing upper bounds onthe coupling-mass relation by assuming exchanges of scalar and pseudoscalarfields at a 95 % confidence level in the sub-eV mass range.
