A. Hasegawa et al., POLARIZATION DEPENDENCE OF 3-PULSE 4-WAVE-MIXING AT THE EXCITON RESONANCE - QUANTUM BEAT AND POLARIZATION INTERFERENCE, Progress in crystal growth and characterization of materials, 33(1-3), 1996, pp. 93-96
The polarization dependence of 3-pulse four wave mixing (FWM) at the e
xciton resonance has been studied in GaSe. A quantum beat modulation c
an be observed in 3-pulse FWM signals. The polarization dependence of
the quantum beat has also been studied. The quantum beat and the polar
ization interference can be experimentally distinguished by the time-i
ntegrated 3-pulse FWM.
