We demonstrate quantum interference control of injected photocurrents in a semiconductor using the phase stabilized pulse train from a mode-locked Ti:sapphire laser. Measurement of the comb offset frequency via this technique results in a signal-to-noise ratio of 40 dB (10 Hz resolution bandwidth), enabling solid-state detection of carrier-envelope phase shifts of a Ti:sapphire oscillator.
我们利用锁模钛宝石激光器产生的相位稳定脉冲序列，展示了对半导体中注入光电流的量子干涉控制。通过该技术对频率梳偏移频率的测量，得到了40分贝的信噪比（10赫兹分辨率带宽），从而能够对钛宝石振荡器的载流子包络相位偏移进行固态检测。
