Steering ultrafast electron dynamics with well-controlled laser fields is very important for generation of intense supercontinuum radiation.It can be achieved through coherent control of the symmetry of the interaction between strong-field laser fields and a metal nanotip.We employ a scheme of two-color laser pulses combined with a weak static field to realize the control of a single quantum path to generate high harmonic generation from a single solid-state nanoemitter.Moreover,a smooth and ultrabroad supercontinuum in the extreme ultraviolet region is obtained,which can produce a single attosecond pulse.Our findings are beneficial for efficient generation of isolated sub-100 as XUV pulses from solid-state sources.
