      abstract     = {Focusing petawatt-level laser beams to a variety of spot
                      sizes for different applications is expensive in cost, labor
                      and space. In this paper, we propose a plasma lens to
                      flexibly resize the laser beam by utilizing the laser
                      self-focusing effect. Using a fixed conventional focusing
                      system to focus the laser a short distance in front of the
                      plasma, we can adjust the effective laser beam waist within
                      a certain range, as if a variety of focusing systems were
                      used with the plasma lens acting as an adjustable eyepiece
                      in a telescope. Such a setup is a powerful tool for laser
                      wakefield accelerator experiments in state-of-art petawatt
                      laser projects and allows for scanning focal spot
