Highly efficient terahertz generation using 3D Dirac semimetals
Lu Wang, Jeremy Lim, Liang Jie Wong
We show that 3D Dirac semimetals are promising candidates for highly efficient optical-to-terahertz conversion due to their extreme optical nonlinearities. In particular, we predic…
Tilted-pulse-front schemes for terahertz generation
Lu Wang, György Tóth, János Hebling +1
High energy single- to few-cycle terahertz pulses enable the exploration of the frontier of science, such as electron acceleration, strong-field physics, and spectroscopy. One impo…
Full 3D+1 modelling of the tilted-pulse-front setups for single-cycle terahertz generation
Lu Wang, Tobias Kroh, Nicholas H. Matlis +1
The tilted-pulse-front setup utilizing a diffraction grating is one of the most successful methods to generate single- to few-cycle terahertz pulses. However, the generated teraher…
High Efficiency Terahertz Generation in a Multi-Stage System
Lu Wang, Arya Fallahi, Koustuban Ravi +1
We describe a robust system for laser-driven narrowband terahertz generation with high conversion efficiency in periodically poled Lithium Niobate (PPLN). In the multi-stage terahe…
