Multi-Cycle THz Pulse Generation and Manipulation in Poled Lithium Niobate

Abstract

We have developed novel schemes to generate and manipulate multi-cycle THz pulses via optical rectification in orientation inverted nonlinear crystals such as poled lithium niobate. Exploiting the methods, we have demonstrated generation of tunable narrow-band THz pulses, adaptive THz pulse shaping, and arbitrary control of THz ellipticity.
