We explore the efficacy of two single-repumping schemes, 5 s 5 p P 2 3− 5 p 2 P 2 3 (481
nm) and 5 s 5 p P 2 3− 5 s 5 d D 2 3 (497 nm), for a magneto-optical trap (MOT) of Sr atoms …

Quantum dynamics of a collection of atoms subjected to phase modulation has been
carefully revisited. We present an exact analysis of the evolution of a two-level system …

Compact and robust optical clocks are significant in scientific research and engineering.
Here, we present a physical system for a strontium atomic optical clock with dimensions of …

To rapidly improve strontium optical clocks, a high-power, high-efficiency, and high-beam-
quality 461 nm laser is required. In blue lasers based on periodically poled KTiOPO4 …

The presence of ultra-narrow inter-combination spectroscopic lines in alkaline earth
elements places them as promising candidates for optical atomic clocks, quantum …

Abstract A Bose Einstein Condensate (BEC) is an extraordinarily versatile state of matter that
allows for the simulation of quantum phenomena on the macroscopic scale. This powerful …

Mobile ad hoc networks (MANETs), drone-based wireless networks, or wireless sensor
networks (WSNs) consisting of nodes with single omnidirectional antennas and limited …

Using a simple and cost-effective water-jet process, we have overcome silicon etch depth
limitations to realize a 6 mm deep atomic vapor cell. We have successfully used this …
