	A free-electron laser (FEL) may be obtained by interaction of an electron bunch and a nearly copropagating laser pulse, where the laser pulse is sheared to extend the interaction length. When the angle between the electron beam axis and the propagation direction of the laser pulse greatly exceeds the reciprocal of the relativistic factor, the output radiation is nearly on the axis, and the FEL may be approximated by an axially aligned magnetostatic undulator. For a feasible laser-undulator FEL, we calculate gain using a one-dimensional model, as well as a three-dimensional model that includes degradation from diffraction and electron velocity spread.
