Using an affordable ytterbium laser with sub-mJ of energy combined with a novel pulse compression technique, we demonstrate an extremely competitive state-of-the-art terahertz (THz) source with 53 mW of average power and 310 kV/cm at focus from the tilted-pulse front pumping scheme in lithium niobate at room temperature. Key points of this demonstration include the use of a pump pulse duration of 280 fs in combination with an echelon mirror. Our results present unmatched combined…

Terahertz waveform synthesis from integrated lithium niobate circuits
TLDR
This work experimentally demonstrates that thin-film lithium niobate (TFLN) circuits provide a versatile solution for waveform synthesis through combining the merits of complex integrated architectures, low-loss distribution of pump pulses on-chip, and an e-cient optical recti-cation.

Effect of extreme pump pulse reshaping on intense terahertz emission in lithium niobate at multimilliJoule pump energies.
TLDR
The findings show a series of key problems that must be overcome before the theoretical limit can be achieved, including the influence of the pump bandwidth broadening due to the cascaded nonlinearity taking place within the crystal.
