Highly efficient narrowband terahertz generation driven by a two-spectral-line laser in PPLN
H. T. Olgun, W. Tian, G. Cirmi +7
We demonstrate record conversion efficiencies of up to 0.9 percent for narrowband (1 percent relative bandwidth) THz generation by strongly-cascaded difference frequency generation…
Pulse Sequences for Efficient Multi-Cycle Terahertz Generation in Periodically Poled Lithium Niobate
Koustuban Ravi, Damian N. Schimpf, Franz X. Kärtner
The use of laser pulse sequences to drive the cascaded difference frequency generation of high energy, high peak-power and multi-cycle terahertz pulses in cryogenically cooled peri…
Cascaded Parametric Amplification for Highly Efficient Terahertz Generation
Koustuban Ravi, Michael Hemmer, Giovanni Cirmi +4
A highly efficient, practical approach to high-energy terahertz (THz) generation based on spectrally cascaded optical parametric amplification (THz-COPA) is introduced. The THz wav…
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…
