Radially Polarized Terahertz Beam Emission by Difference Frequency Generation in GaAs

Not Accessible

Your library or personal account may give you access

Abstract

It is shown that using quasi-phase-matched GaAs crystal in the scheme of Cherenkov- type difference frequency generation allows controlling the direction of terahertz emission and by that way achieving significant increase in the output power.
