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…
Half-percent terahertz generation efficiency from cryogenically cooled lithium niobate pumped by Ti:sapphire laser pulses
Xiaojun Wu, Koustuban Ravi, Wenqian Ronny Huang +6
We obtained an optical-to-terahertz (THz) energy conversion efficiency of 0.5% using the tilted-pulse-front technique in lithium niobate at a cryogenically cooled temperature of 10…
Terahertz-driven linear electron acceleration
Emilio Alessandro Nanni, Wenqian Ronny Huang, Kyung-Han Hong +5
The cost, size and availability of electron accelerators is dominated by the achievable accelerating gradient. Conventional high-brightness radio-frequency (RF) accelerating struct…
Theory of THz generation by Optical Rectification using Tilted-Pulse-Fronts
Koustuban Ravi, Wenqian Ronny Huang, Sergio Carbajo +4
A model for THz generation by optical rectification using tilted-pulse-fronts is developed. It simultaneously accounts for (i) the spatio-temporal distortions of the optical pump p…
Limitations to THz generation by optical rectification using tilted pulse fronts
Koustuban Ravi, Wenqian Ronny Huang, Sergio Carbajo +2
Terahertz (THz) generation by optical rectification (OR) using tilted-pulse-fronts is studied. One-dimensional (1-D) and 2-D spatial models, which simultaneously account for (i) th…
