Place a cylindrical lens in front of it. A glass stirring rod would work, or an acrylic rod, or a wine glass stem, or a small bottle filled with water, etc.

Above works or you can make from a
small cpu or PC casing fan, mount a mirror perpendicular to the fan, reflecting a laser should make a line.
A cylinder like cameron suggests, or a diffraction grating designed to crate a straight line.
