We describe a novel Zeeman slowing method reported in (Petzold et al (2018 New J. Phys. 20 042001)) and compare it to conventional radiative beam slowing schemes. The scheme is designed to work on a type-II level structure making it…

We proposed a general Zeeman slower scheme applicable to the majority of the laser-coolable molecules. Different from previous schemes, the key idea of our scheme lies in that the compensation of the detuning with the magnetic field is done…
