Abstract: Using the WKB approximation and paraxial model, we investigated the effect of electron temperature on interaction of 527 nm intense laser and plasmas. The results show that, the electron temperature presents an oscillation variation, and dielectric constant also presents an oscillation variation and leads to laser width presents steady separation, oscillation separation and selffocusing in plasmas.
