ABSTRACT
A novel mechanism of generating synchrotron radiation by relativisticaily strong laser fields is proposed. We show that an electron injected externally with an appropriate velocity into a circularly polarised laser beam will keep circulating in an orbit perpendicular to the the laser beam. The electron then radiates in a similar way as electrons in the storage ring of synchrotron accelerator. Due to the small orbit radius in the laser field, ”laser-driven synchrotron radiation” can become a powerful source of short-wavelength coherent radiation.
