This left only a slim window – a few femtoseconds – where the laser  was reflected.

这只留下了一个很小窗口（几飞秒），反射。

Katherine strode briskly into the main lab. The bright and sterile work space glistened with advanced quantitative equipment: paired electro encephalographs, a femtosecond comb, a magneto-optical trap, and quantum-indeterminate electronic noise REGs, more simply known as Random Event Generators.

Katherine快步走进主实验室。明亮而无工作空间闪闪发，配备了先进设备：成对脑电图、飞秒梳、磁阱和子不确电子噪声 REG，更简单地称为随机事件发生器。
