The buleshift properties of high-harmonic generation with phase matching of different filling pressures and laser intensities are experimentally investigated in this paper. The laser buleshift generated in gas cell, with about 0.13 nm in plateau and 0.07 nm in cutoff is obtained. The buleshift is influenced by simply changing the filling pressure and laser intensity, namely, by varying the density of free electrons in gas cell.
