Recent progress of the high peak power laser technology allows us to explore the possibility to apply such lasers for fundamental physics. We focus on topics of high energy electron acceleration for colliders, an straw-man proposal to test the Lorentz invariance at ultra-high energy, and a novel technique to enhance focused laser intensity by flying mirrors. We review the experimental results of laser wakefield acceleration (LWFA) and the possibility to apply LWFA for TeV linear colliders. One of the key issues is the lack of driving laser technology to fulfill the requirement in terms of luminosity. If we seek another application taking the advantage of LWFA to reach ultra-high energy, we can propose a test of -ray's velocity dependence on its energy as expected in some of quantum gravity theories. Finally we give the review of flying mirror schemes, which may boost the laser focused intensity.
