低功率水平下的相位控制光开关
Phase controlled light switching at low power levels
摘要：
我们报道了四能级系统中三光子和单光子激发之间的干涉以及光衰减/透射的相位控制的实验观察。通过改变弱控制激光的相位和/或频率，可以获得相长干涉或相消干涉。这种干涉使得一个场能够在不同频率和超低光水平下被另一个场吸收切换。
英文摘要：
We report experimental observations of interference between three-photon and one-photon excitations, and phase control of light attenuation/transmission in a four-level system. Either constructive interference or destructive interference can be obtained by varying the phase and/or frequency of a weak control laser. The interference enables absorptive switching of one field by another field at different frequencies and ultra-low light levels.
