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, Chul Kang, and Ki-Yong Kim

Abstract

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 pulses. Such terahertz radiation is produced by phase-matched optical rectification in lithium niobate. Experimentally, we achieve maximal terahertz energy of 0.71 mJ with conversion efficiency of ${\sim}0.04\%$. Our experimental setup is simple and easily upscalable to produce multi-millijoule, multicycle terahertz radiation with proper lithium niobate crystals.
