Ultrafast, high repetition rate, ultraviolet, fiber based laser source: application towards Yb+ fast quantum-logic
Mahmood Irtiza Hussain, Matthew Joseph Petrasiunas, Christopher D. B. Bentley +6
Trapped ions are one of the most promising approaches for the realization of a universal quantum computer. Faster quantum logic gates could dramatically improve the performance of…
Effects of flake size on mode-locking behavior for flake-graphene saturable absorber mirrors
M. I. Hussain, B. V. Cunning, L. S. Booth +3
After advent of graphene as a saturable absorber many experiments have been conducted to produce short pulse duration pulses. Here, we have measured the properties of flake-graphen…
Three-photon excitation of quantum dots with a telecom band ultrafast fiber laser
M. J. Petrasiunas, J. B. O. Wood, D. Kielpinski +1
We demonstrate three-photon excitation in quantum dots with a mode-locked fiber laser operating in the telecommunications band. We compare spectra and intensity dependence of fluor…
Optogalvanic Spectroscopy of Metastable States in Yb^{+}
M. J. Petrasiunas, E. W. Streed, T. J. Weinhold +2
The metastable ^{2}F_{7/2} and ^{2}D_{3/2} states of Yb^{+} are of interest for applications in metrology and quantum information and also act as dark states in laser cooling. Thes…
Millikelvin Spatial Thermometry of Trapped Ions
B. G. Norton, E. W. Streed, M. J. Petrasiunas +2
We demonstrate millikelvin thermometry of laser cooled trapped ions with high-resolution imaging. This equilibrium approach is independent of the cooling dynamics and has lower sys…
Wavelength-Scale Imaging of Trapped Ions using a Phase Fresnel lens
A. Jechow, E. W. Streed, B. G. Norton +2
A microfabricated phase Fresnel lens was used to image ytterbium ions trapped in a radio frequency Paul trap. The ions were laser cooled close to the Doppler limit on the 369.5 nm…
