Recently, advancement of laser technology has enabled the generation of PW pulses, which is opening the door to the new regime of laser-particle accelerations. In this talk, the author presents a new method to stabilize multi-GeV electron beams by manipulating the spectral phase of PW laser pulses, coherently controlling the laser wake-field acceleration process. They have demonstrated the stable generation of 2-GeV electron beams in a 1-cm gas cell of He using the PW Ti:Sapphire laser system. PB - JACoW CP - Geneva, Switzerland ER -
