Abstract
Methods and apparatus are disclosed for directing optical radiation to make multiple passes across an extended region of an electro-optic material, where during each pass the electro-optic material converts a portion of the optical radiation into terahertz radiation, and where the optical radiation is directed into the electro-optic material to cause an amplitude of the terahertz radiation generated from one or more earlier passes of the optical radiation to be constructively enhanced by the terahertz radiation generated from a later pass of the optical radiation.
