    "abstract": "We present a time-dependent perturbative approach adapted to the treatment of\nintense pulsed interactions. We show there is a freedom in choosing secular\nterms and use it to optimize the accuracy of the approximation. We apply this\nformulation to a unitary superconvergent technique and improve the accuracy by\nseveral orders of magnitude with respect to the Magnus expansion.",
