We present progress towards an ultra-low phase noise microwave synthesizer, critical for achieving high-precision quantum gravimeters and gyroscopes based on cold-atom interferometry. The microwave synthesizer is used both for laser cooling ⁸⁷Rb atoms and inducing ground-state Raman transitions that function as momentum-transfer pulses in our atom interferometer. During these pulses, the phase...
We demonstrate a method for stabilizing a diode laser using a frequency-offset locking scheme and commercial electronics. Our 1560 nm diode laser is slaved to an ultra-stable master laser operating at 780 nm by frequency-doubling the slave laser and measuring its optical beatnote with the master on a high-speed photodiode. This RF beatnote is fed through a broadband variable divider and a...
Multi-frequency Raman generation (MRG) is a high order stimulated Raman process that can produce ultrashort laser pulses with high intensities. In experimental realizations of MRG, phenomena arise such as a single sideband shifted to a lower frequency on each of the Raman order peaks. These phenomena are not explained by previous theory. We derive analytic expressions for properties of MRG,...
The TRIUMF polarizer facility provides nuclear-spin-polarized radioactive isotopes via collinear optical pumping for physical and biomedical science$^{[1]}$. Recently, more exotic isotopes, such as $^{32}$Na and $^{230,232}$Ac, with production rates below ~1000 s$^{-1}$, are demanded to be highly spin-polarized to study nuclear structure and develop radiopharmaceuticals for cancer treatment....
Nonlinear laser fiber amplification is a powerful technique known for generating high-energy, ultrashort pulses efficiently and compactly, finding applications in various fields. In this study, our objective is to develop and optimize a two-color nonlinear amplification system, which will serve as a crucial component for future multi-frequency Raman generation (MRG) experiments. The...
We present our progress towards developing a trapped ion quantum information processor and describe our robust hardware and software architecture. Our platform for storing and processing quantum information is trapped Barium ions. Because of long-lived ground and metastable atomic states and transitions in the visible wavelengths, Ba$^+$ offers exciting possibilities to encode quantum...
