原子激光由粒子组成,但它像一切波现象那样拥有频率和波长（两上相邻波峰间的距离）.激光是相干的,因为它们是受激发射的电磁波,它们的电磁波的波峰与激发它们的光波相一致.这种现象就提供了获得更大能量光束的可能性.
为了将原子冷却至接近绝对零度，物理学家倚靠的是雷射及磁场组成的系统来局限原子。
To cool atoms to near absolute zero, physicists rely on systems of lasers and magnetic fields to trap atoms.
光子与矽原子发生零星碰撞并释放自由电子时，矽拉曼雷射的功率也会随之到达极限。
The power of a silicon Raman laser typically hits a limit as photons sporadically collide with silicon atoms and release free electrons.
通过把光子束注入暗室生成雷射。管理雷射原子的能态，以控制其输出。
