研究目的
To develop a self-pumping high-vacuum MEMS optical cell for cold Rb/Cs atoms spectroscopy, achieving dynamically stabilized high vacuum inside the cell in the presence of rubidium vapors.
研究成果
The presented self-pumping MEMS cell for atomic spectroscopy is a groundbreaking solution, achieving a vacuum level of 10-7 Torr and dynamically stabilizing it at 10-6 Torr in the presence of rubidium vapors. This opens new possibilities for fabricating optical cells for atomic spectroscopy.
研究不足
The initial vacuum after the sealing process is 1xE-3 Torr, and achieving better vacuum requires optimization of applied voltage and pumping time. The true potential of the solution needs to be demonstrated through more sophisticated experiments like cold atoms spectroscopy.
