We use the Lewenstein model to study the high harmonic generated for a μp atom exposed to two-color XUV pulses. Calculated results show a super continuum plateau in high harmonic spectrum which is formed when the time delay is 0 and XUV frequencies are 5 and 2.5. By synthesizing the continuous high harmonic spectra, a pulse as short as 130 zeptosecond is obtained. Such a single zeptosecond pulse may work as an ultrafast camera to capture ultrafast processes occurring inside nuclei.
