We observed extreme ultraviolet (XUV) continuum radiation generated by using a sub-10-fs two-color pulse. When a laser field consisting of fundamental and its second harmonic pulses with parallel polarization was applied to high-order harmonic generation in argon, a continuum spectrum centered at 30 nm was obtained with an energy as high as 10 nJ. The broadband radiation indicates the possibility of generating powerful single attosecond pulses in the XUV region.
