Generation of 0.7 mJ multicycle 15 THz radiation by phase-matched optical rectification in lithium niobate
Dogeun Jang, Jae Hee Sung, Seong Ku Lee +2
We demonstrate efficient multicycle terahertz pulse generation at 14.6 THz from large-area lithium niobate crystals by using high-energy (up to 2 J) femtosecond Ti:sapphire laser p…

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…
