The disclosure relates to a fibre-optic mode scrambler for homogenising laser illumination over a short timescale. Example embodiments include a fibre-optic mode scrambler (100) comprising: a series of fibre guides (103a, 103b, 104a, 104b) arranged to hold a portion of an optical fibre (102) with a defined curvature between a pair of the fibre guides (103a, 103b); an electroactive transducer (101) positioned between the pair of fibre guides (103a, 103b) and arranged to contact the portion of the optical fibre (102) along a contact length of the optical fibre; and a control module (111) arranged to provide a drive signal to the transducer (101).
