The present application relates to generating terahertz radiation, wherein a pump pulse is subjected to pulse front tilting, the thus obtained pump pulse having tilted pulse front is coupled into a nonlinear optical medium and THz pulse is generated by the optical medium in nonlinear optical processes, particularly by means of optical rectification by the pump pulse. The application also relates to a terahertz radiation source (), comprising a pump source () for emitting a pump pulse and a nonlinear optical medium for generating THz pulse. The pump source () and the nonlinear optical medium define together a light path, said light path is arranged to guide the pump pulse from the pump source () to the nonlinear optical medium. A first optical element () having angular-dispersion-inducing property and imaging optics () are disposed in the light path after each other in the propagation direction of the pump pulse.
