摘要：

Amplitude and phase-controlled midinfrared field transients at a wavelength of 12.5 mum induce resonant intersubband excitations in n-type modulation-doped GaAs/AlGaAs quantum wells. The transmitted electric field transients are directly measured by ultrafast electro-optic sampling. Coherent control of intersubband excitations is demonstrated by applying two phase-locked pulses with variable relative phase. A coherent nonlinear response corresponding to partial Rabi flops of up to 60 degrees in the Bloch sphere is observed with excitation pulses of only 1 pJ energy.
