The transient properties of electromagnetically induced transparency (EIT) are studied with different probe pulse energies for the first time in the 3S 3P 3/2 4D ladder type three level system of sodium atom.The EIT effect would be reduced with the increase of the probe pulse energy. Theoretical calculation is carried out by solving the time dependent matrix equation. The experimental results agree well with the theoretical calculation.
