Abstract
A pump beam () is subjected to pulse front tilting, and then guided through an imaging optics () and then coupled into the nonlinear optical medium through an entry surface of the nonlinear optical medium. THz radiation is generated in the optical medium by nonlinear optical processes, in particular by optical rectification, via the pump beam. The pulse front tilt of the pump beam required to satisfy the velocity matching condition of vcos(γ)=vis induced as a sum of a plurality of pulse front tilts, where each pulse front tilt is induced separately as a partial pulse front tilt of the pump beam in subsequent steps. The last step of pulse front tilting of said pump beam () is performed by coupling the pump beam () into the nonlinear optical medium through a stair-step structure () formed in the entry surface of the nonlinear optical medium.
