Query: Fundamental Physics Explored with High Intensity Laser   Over the last Century the method of particle acceleration to high energies
has become the prime approach to explore the fundamental nature of matter in
laboratory. It appears that the latest search of the contemporary accelerator
based on the colliders shows a sign of saturation (or at least a slow-down) in
increasing its energy and other necessary parameters to extend this frontier.
We suggest two pronged approach enabled by the recent progress in high
intensity lasers.
