Abstract: We performed an experiment of high brightness gamma(γ)-rays production through laser-electron(e^{-}) collisions using an insertion device with a short focal length of laser optics. Number of generated γ-rays with the bunch length of 26 psec (r.m.s) was 0.92 × 10^5/bunch, thus leading to brightness 2.5 × 10^{17}/(mm^2 · mrad^2 · 0.1% band-width · sec). Quantitative considerations on the basis of numerical model permitted to elucidate how characteristics of ^{-} and laser beam influence collision mechanisms.
