Scalable terahertz generation by large-area optical rectification at 80 TW laser power

Dogeun Jang, Chul Kang, Seong Ku Lee +3

We demonstrate high-energy terahertz generation from a large-aperture (75 mm diameter) lithium niobate wafer by using a femtosecond laser with energy up to 2 J. This scheme utilize…
