Examining the reflection and transmission of pulses by a half-space occupied by an axially excited cholesteric liquid crystal (CLC), we uncover the spatio-temporal anatomy of the circular Bragg phenomenon exhibited by CLCs. In particular, we show the phenomenon of pulse bleeding occurs in the Bragg regime, when the handedness of the incident light coincides with the structural handedness of the illuminated CLC.
