用于除雾的分子量子尾流
Molecular Quantum Wakes for Clearing Fog
摘要：
最近，在空气中的高强度激光照射已经证明，通过等离子体的产生及其相关的冲击波，可以清除光束周围的雾，留下光学透明的路径来传输光。然而，对于像自由空间光通信（FSO）这样的实际应用，需要在千米范围内具有多厘米直径的信道，这对于基于等离子体的方法是极其具有挑战性的。在这里，我们报告了一种完全不同的方法，基于量子控制。我们证明，雾清除也可以通过在空气中产生分子量子尾流来实现，并且既不需要等离子体产生也不需要等离子体。这种效应与N2中旋转波包的复相时间有关。以8个脉冲的共振串形式提供的泵浦光激励，其初始消光系数可达-6dB。
英文摘要：
High intensity laser filamentation in air has recently demonstrated that, through plasma generation and its associated shockwave, fog can be cleared around the beam, leaving an optically transparent path to transmit light. However, for practical applications like free-space optical communication (FSO), channels of multi-centimeter diameters over kilometer ranges are required, which is extremely challenging for a plasma based method. Here we report a radically different approach, based on quantum control. We demonstrate that fog clearing can also be achieved by producing molecular quantum wakes in air, and that neither plasma generation nor filamentation are required. The effect is clearly associated with the rephasing time of the rotational wave packet in N2.Pump excitation provided in the form of resonant trains of 8 pulses separated by the revival time are able to transmit optical data through fog with initial extinction as much as -6 dB.
