Using the AdS/CFT correspondence, we study finite ’t Hooft coupling corrections on the instantaneous energy loss of light quarks within shooting string. We consider the first higher-derivative corrections to the supergravity theory, which are 
terms in the gravity action. It turns out that the energy loss decreases with decreasing 
(’t Hooft coupling constant), in agreement with previous findings of the light quarks energy loss obtained from the jet quenching parameter and stopping distance. In addition, we discuss how the energy loss changes with the shear viscosity to entropy density ratio at strong coupling.
