The circular dichroism (CD) and circular diffraction through chiral atomic medium pulses are measured controlled and modified. The CD is equal to 
and birefringence 
, and phase shift dichroism 
is manipulated with probe field detuning and control field parameters in chiral medium. The CD is measured from 
to 0.004 mA (milli Absorbance). The phase and group birefringence is measured in the range of 
and 
while the delay of the pulses is measured from 
to 
μs. Similarly, the variation in phase shift and group phase shift dichroism is measured in the range of 
and 
microradian. The phase divergent angle and group divergent angle between two circular polarized beams are noted in the range of 
and 
microradian while the phase diffractive angle and group diffractive angle are measured as 
and 
microradian per 1/10 of micrometer length of the medium. These results will play a significant role in sensors devices and gravitational waves detection.
