Terahertz generation in an actively controlled femtosecond enhancement cavity

M. Theuer, D. Molter, K. Maki, C. Otani, J. A. L'huillier et al.
We report on terahertz generation by Cherenkov-type optical rectification in lithium niobate using an actively controlled femtosecond pumped enhancement cavity. In this way a much higher pump power is available inside the cavity and an increased terahertz output power is obtained. The advantages of ... [Appl. Phys. Lett. 93, 041119 (2008)] published Fri Aug 1, 2008.
