MATCHED PULSES AND ELECTROMAGNETICALLY INDUCED TRANSPARENCY FOR THE INTERACTION OF LASER PULSE PAIRS WITH A DOUBLE-VEE SYSTEM

摘要

We demonstrate the occurrence of electromagnetically induced transparency with pulse matching in the propagation of two probe pulses through a double-vee (DV) system prepared by a pair of strong coupling fields. Pulse matching is connected to the phenomenon of coherent population trapping. We show that the space-time evolution of the probe pulses is determined by a pair of normal modes that describe the propagation of the pulsed excitation through the medium. The establishment of the pulse-matching propagation regime and the transparency for the probe pulses are related to the absorption properties of the normal modes. [References: 15]
