The generation of isolated attosecond XUV pulses has been established in recent years [1]. More recently, the generation of few-cycle low-order harmonics has been demonstrated: sub-4 fs UV pulses are produced by third and fifth harmonic generation of few-cycle near-infrared (NIR) laser pulses in a gas target [2]. Now we investigate the possibility of the simultaneous generation of low-order harmonics and high-harmonic by two subsequent gas targets in a collinear geometry. Future experiments employing these unique light pulses for the study and control of electronic motion in nano-structured semiconductors will be discussed.
