Controlled guiding of laser pulses at relativistic intensities in plasmas over distances exceeding the diffraction length is a crucial requirement of a Laser Plasma Accelerator Stage (LPAS) for achieving high quality electron beams. A hybrid guiding scheme is proposed using a dielectric capillary tube, inside which a plasma channel is generated. A high intensity laser (I = 4.3x10 18 W/cm 2 ) focused at the entrance of this structure can be efficiently guided by the combined refraction of this channel and reflection at capillary walls. The efficiency of this guiding scheme as a LPAS has been investigated through numerical simulations of a 10 pC electrons beam injected at 150 MeV and accelerated up to 1.9 GeV inside a plasma channel of density 1.5x10 17 e.cm −3 and of 15 cm length.
