  We investigate laser-induced torques in magnetically non-collinear
ferromagnets with a spin-spiral magnetic structure using \textit{ab-initio}
calculations. Since spin-spirals may be used to approximate the magnetization
gradients locally in domain walls and skyrmions, our method may be used to
obtain the laser-induced torques in such objects from a multiscale approach.
Employing the generalized Bloch-theorem we obtain the electronic structure
computationally efficiently. We employ our method to assess the laser-induced
torques in bcc Fe, hcp Co, and L$_{1}0$ FePt when a spin-spiral magnetic
structure is imposed. We find that the laser-induced torques in these
magnetically noncollinear systems may be orders of magnitude larger than those
in the corresponding magnetically collinear systems and that they exist both
for linearly and circularly polarized light. This result suggests that
laser-induced torques driven by noncollinear magnetic order or by magnetic
fluctuations may contribute significantly to processes in ultrafast magnetism.
