Pulse Breathing Dynamics in a Mode-Locked Laser measured via SHG autocorrelation
S. Kannan, S. Padmanaban, X. T. Yan +4
Pulse-to-pulse fluctuations in mode-locked lasers fundamentally limit applications from optical frequency combs to supercontinuum generation. While timing jitter has been extensive…
Measurement of a helium tune-out frequency: an independent test of quantum electrodynamics
B. M. Henson, J. A. Ross, K. F. Thomas +9
Despite quantum electrodynamics (QED) being one of the most stringently tested theories underpinning modern physics, recent precision atomic spectroscopy measurements have uncovere…
Frequency measurements of transitions from the state to the , , and states in ultracold helium
Jacob A. Ross, Kieran F. Thomas, Bryce M. Henson +4
We perform laser absorption spectroscopy with ultracold He atoms to measure the energy intervals between the level and five levels in the n = 5 manifold. The lase…
QED and relativistic nuclear recoil corrections to the 413 nm tune-out wavelength for the state of helium
Yong-Hui Zhang, Fang-Fei Wu, Pei-Pei Zhang +4
Comparison of high accuracy calculations with precision measurement of the 413 nm tune-out wavelength of the He() state provides a unique test of quantum electro-dynamic…
Widely tunable, narrow linewidth external-cavity gain chip laser for spectroscopy between 1.0 - 1.1 um
Dong K. Shin, Bryce M. Henson, Roman I. Khakimov +5
We have developed and characterised a stable, narrow linewidth external-cavity laser (ECL) tunable over 100 nm around 1080 nm, using a single-angled-facet gain chip. We propose the…
Ghost Imaging with Atoms
R. I. Khakimov, B. M. Henson, D. K. Shin +4
Ghost imaging is a technique -- first realized in quantum optics -- in which the image emerges from cross-correlation between particles in two separate beams. One beam passes throu…
Precision Measurement for Metastable Helium Atoms of the 413 nm Tune-Out Wavelength at Which the Atomic Polarizability Vanishes
B. M. Henson, R. I. Khakimov, R. G. Dall +3
We present the first measurement for helium atoms of the tune-out wavelength at which the atomic polarizability vanishes. We utilise a novel, highly sensitive technique for precise…
