Description	Journal: Plasma Physics and Controlled Fusion Laser pulses facilitate multiphoton contributions to the trident pair production $eL-\toeL-+eL++eL- , where the label L indicates a laser field dressed electron (e$ ^{-}$) or positron (e$ ^{+}$ ). We isolate the impact of the pulse envelope in the trident S matrix element, formulated within the Furry picture, in leading order of a series expansion in the classical nonlinearity parameter a$ _{0}$. Generally, the Fourier transform of the envelope carries the information on the pulse length, which becomes an easily tractable function in the case of acos2 pulse envelope. The transition to a monochromatic laser wave can be handled in a transparent manner, as also the onset of bandwidth effects for short pulses can be factorized out and studied separately.$
