EFFECTS OF LASER PULSE SHAPE AND BEAM PROFILE ON ELECTROMAGNETICALLY-INDUCED TRANSPARENCY Publication No.

Supervising Professor: Cyrus D. Cantrell Effects of a Gaussian pulse shape and beam profile on Electromagnetically-Induced Trans-parency (EIT) are studied in a strong probe laser intensity regime under the context of laser pulse propagation. By adopting a pulse-sequencing method, we show that EIT for an intense probe laser can be realized when both incident laser envelopes having both temporal and transverse radial profiles. A proper selection of two relevant parameters, i.e. time peak location and beam diameter, of two injected lasers will implement this pulse-sequencing technique into our numerical experiments on EIT and lead to an enhanced EIT behavior for a strong probe laser beam. vi TABLE OF CONTENTS Dedication....................................................................... i
