Abstract

We demonstrated efficient multi-cycle terahertz generation centered at 0.5 THz with periodically poled lithium niobate crystals via difference frequency generation with a multiple-frequency-line source. At 130 mJ/cm² pump fluence, the internal optical-to-THz conversion efficiency reaches 0.3%.
