Abstract
We report on an actively controlled enhancement cavity for terahertz generation using optical rectification in lithium niobate. By recycling the transmitted fundamental laser power from a Ti:Sapphire laser an increased pump power is available for the nonlinear process. Therefore a much higher THz signal is obtained in relation to single-pass geometry. Terahertz intensities generated by different emitters are compared with Cherenkov-type generation in the enhancement cavity.
