The finite-amplitude short coherent control pulse with small random errors in its direction is considered. We derive the conditions for it to approximate an ideal delta-shaped pulse up to an error in the second order of pulse duration. How well the symmetric and asymmetric pulse shapes would satisfy these conditions is also analyzed. The result shows that symmetric pulse shape performs better than asymmetric pulse under certain conditions.
