Laser-plasma produced by ultraintense femtosecond laser pulses is an emerging particle acceleration technology which promises a revolutionary impact in the field of high-energy particle accelerators. Electric fields inside a plasma bubble created by intense ultrashort laser pulse can be several orders of magnitude higher than those available in conventional RF-based particle accelerator facilities. Therefore, an electron bunch can gain relativistic energies within an extremely short distance. We present results* that demonstrate the first generation of stable and reproducible sub GeV, GeV and beyond 1 GeV electron beams from a few-millimeters long plasma channels produced by self-guided laser pulses in gas jet targets. The qualities of those electron beams are now approaching the requirements for applications such as compact synchrotrons and FELs. Based on our laser-plasma electron beams, we are planning on building undulators at APRI aiming to realize compact synchrotron and FEL light sources.
