Toward the systematic search for axion-like particles in the eV mass range, we proposed the concept of a stimulated resonant photon collider by focusing three short pulse lasers into vacuum. In order to realize such a collider, we have performed a proof-of-principle experiment with a set of large incident angles between three beams to overcome the expected difficulty to ensure the space-time overlap between short pulse lasers and also established a method to evaluate the bias on the polarization states, which is useful for a future variable-incident-angle collision system. In this paper we present a result from the pilot search with the developed system and the method. The search result was consistent with null. We thus have set the upper limit on the minimum ALP-photon coupling down to 1.5 × 10-4 GeV-1 at the ALP mass of 1.53 eV with a confidence level of 95 %.
