Programmable fabrication of longitudinal spatial structures in an optically preformed plasma waveguide in a gas jet was achieved, by using laser machining with a liquid-crystal spatial light modulator as the pattern mask. Fabrication of periodic structures with a minimal period of 200 lm and density-ramp structures with a minimal slope length of 100 lm was attained. The technique is useful for the optimization of various laser-plasma-based photon and particle sources.
