The birefringence cratering of reflection, transmission and corresponding Goos Hänchen (GH) shift are investigated in reflection and transmission beams through four level chiral atomic medium of structured light. The reflection and transmission of left and right circularly polarized light obey normalization condition and strong cratering oscillation functions of positions and azimuthal quantum number 
of control field. Crater types reflection and transmission are investigated whose numbers increase with azimuthal quantum numbers having varying in shapes. The GH shifts in reflection and transmission is positive and oscillated with position 
and 
. The numbers of crater in GH shifts depend on the azimuthal quantum number of control field. The values of both GH shift in reflection and transmission varies in the range of 
and 
with increasing craters to increase azimuthal quantum number of control field. The modified results of the GH shifts are useful for biosensor and plasmonster technology.
