Analysis of terahertz generation using tilted-pulse-fronts
Koustuban Ravi, Franz X. Kärtner
A 2-D spatio-temporal analysis of terahertz generation by optical rectification of tilted-pulse-fronts is presented. Closed form expressions of terahertz transients and spectra in…
Terahertz generation by beamlet superposition
Koustuban Ravi, Benjamin Ofori-Okai, Keith A. Nelson +1
We analytically show how a superposition of beamlets produces terahertz radiation with greater spatial homogeneity and efficiency compared to tilted-pulse-fronts generated by diffr…
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…
