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 2x1017 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 35{mu}m 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.
