摘要

我们将一个低于10fs的强烈脉冲及其在空气中的二次谐波聚焦在一起，产生了从远红外到超过200太赫兹的超宽带相干红外波。时域光谱测量确保了波的相干性。用HgCdTe探测器观察中红外到近红外成分。

Ultrabroadband coherent electric field generation from far infrared to 200 THz using air plasma induced by sub 10 fs pulses

Focusing an intense sub 10 fs pulse together with its second harmonics in air, we have generated ultrabroadband coherent infrared wave ranging from far infrared to over 200 THz. Measurement with time domain spectroscopy assures that the wave is coherent. The mid infrared to near infrared component is observed with an HgCdTe detector.
