论文摘要
我们展示了通过两个光谱失调和相关脉冲的差异混合而产生的光波形的活性载体 - 稳定相（CEP）稳定方案。通过使用两个共同传播近红外生成脉冲列车的频谱重叠部分进行椭圆法，我们将它们的相对时间稳定在18时。因此，我们可以将产生的中红外（miR）脉冲的CEP锁定，其余相位抖动低于30 mrad。在散装半导体中采用这些脉冲进行高谐波产生可证明我们的技术。该实验表明，我们的方法还稳定了miR脉冲的能量，从而接近了基础激光系统的内在稳定性。
We demonstrate an active carrier-envelope phase (CEP) stabilization scheme for optical waveforms generated by difference-frequency mixing of two spectrally detuned and phase-correlated pulses. By performing ellipsometry with spectrally overlapping parts of two co-propagating near-infrared generation pulse trains, we stabilize their relative timing to 18 as. Consequently, we can lock the CEP of the generated mid-infrared (MIR) pulses with a remaining phase jitter below 30 mrad. Employing these pulses for high-harmonic generation in a bulk semiconductor validates our technique. This experiment reveals that our method also stabilizes the energy of the MIR pulses, thereby approaching the intrinsic stability of the underlying laser system.
