19 May 2006 Terahertz generation in waveguide partially loaded with nonlinear crystal
Author Affiliations +
We report on the studies of kinetics of broad-band generation via optical rectification into terahertz domain using a sample of LiNbO3 partially filling a hollow metallic waveguide to increase the coherence length, enabling the observation of transition between phase-mismatched and phase-matched mechanisms of terahertz frequency generation.
