We report the development of corrugated ‘slow wave’ plasma guiding structures and discuss their potential application to quasi‐phase‐matched direct laser acceleration of charged particles and generation of a wide spectrum of electromagnetic radiation. These structures support guided propagation at intensities up to 2×1017 W/cm2, limited by our current laser energy and side leakage. Hydrogen and argon plasma waveguides up to 1.5 cm in length with corrugation period as short as 35μm are generated in extended cryogenic cluster jet flows. Side‐imaged scattering of guided intense pulses shows evidence of periodic modulations of the laser pulse intensity.
