Whilst holding great promise for low noise, ease of operation and networking, useful photonic quantum computing has been precluded by the need for beyond-state-of-the-art components, manufactured by the millions. Here we introduce a manufacturable pl

We experimentally measure percent-level optical-to-multi-cycle terahertz conversion efficiencies by injecting a home-made wavelength- and duration-tunable two-line laser into periodically poled lithium niobate. We study the efficiency vs. the input l

High-energy narrowband terahertz (THz) pulses, relevant for a plethora of applications, can be created from the interference of two chirped-pulse drive lasers. The presence of third order dispersion, an intrinsic feature of many high-energy drive las

2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
Millijoule-scale multicycle terahertz (THz) sources have recently gained interest for applications where high-peak-fields and narrow bandwidths can produce unique results, such as linear and nonlinear spectroscopy [1], control of matter [2], and comp

High-Brightness Sources and Light-driven Interactions.
We show improvement of narrowband terahertz generation in periodically poled lithium niobate crystals using chirped-and-delayed pulses from a high energy laser. THz pulses of combined energy above 0.5 mJ at 0.361 THz are generated.
