On December 23 the sun stayed in the sky longer and longer and after that the nights were becoming shorter and shorter. ...

... Свет: остановка по требованию? ... Более мощное "управляющее поле" (свет с правой циркулярной поляризацией) делает возможным распространение в среде на порядок более слабого "сигнального поля" (упоминавшийся выше импульс, свет с левой циркулярной поляризацией), скорость распространения "сигнального импульса" при этом существенно уменьшается. ... Когда часть импульса (I) уже покинула кювету, управляющее поле выключают и из кюветы ничего не выходит до тех пор, пока управляющее поле не включат вновь. ...
