The theoretical and experimental investigation of repumping laser impact on cooling and trapping of strontium atoms

Gao Feng, Chang Hong, Xinliang Wang +2 more

We have conducted experimental investigations on the effect of repumping laser on the cooling and trapping of strontium atoms. More than 3.1×10888Sr atoms have been trapped with 679 nm and 707 nm repumping laser added. The two repumping lasers enhance the trappopulation by a factor of 17. We also made experimental investigations on the effect of 707 nm repumping laser detuning on the cooling and trapping of strontium atoms. The fluctuation of atom trapping population is less than 3 ‰ when the detuning from 707 nm is 5 MHz.We have conducted experimental investigations on the effect of repumping laser on the cooling and trapping of strontium atoms.

Thulium Fibre Lasers for Quantum Applications

Andrea Pertoldi, Poul Varming, Patrick Bowen Montague

Laser cooling is a necessary tool to generate ultracold atoms in magneto-optical traps (MOT), as atomic transitions can be excited with lasers to address different energy levels. As these transitions differ for each quantum system, flexibility in delivering the right wavelength and power at the atoms is key for viable quantum devices or experiments. In our work, we present custom laser systems at the edges of the thulium emission range for improving barium and strontium atoms trapping experiments [1]. Two of barium's narrow atomic transitions can be directly addressed with lasers at 1762 nm and 2052 nm, while third harmonic generation from 2067 nm and 2095 nm allows to address the red MOT cooling and the clock transitions in strontium at 689 nm and 698 nm.Laser cooling is a necessary tool to generate ultracold atoms in magneto-optical traps (MOT), as atomic transitions can be excited with lasers to address different energy levels.
