Fast, simple, all-optical production of sodium spinor condensates

We present an experiment for quickly producing Bose-Einstein condensates (BECs) of Na-23 atoms in a simple crossed dipole trap. The atoms were collected in a magneto-optical trap from a zero-crossing Zeeman slower. The atoms are then transferred to a tightly focused crossed optical dipole trap, and a pure F = 1 BEC of similar to 1.1 x 10(5) sodium atoms was created by a fast forced evaporation. Our system reliably generates the condensate at a rate exceeding 10(5) atoms every similar to 8 s. We also compare the lifetimes of the mixed F = 1 condensate and the spin components (m ( F ) = 0, m ( F ) = +1).

Automated summary

The experiment presents a method for quickly producing Bose-Einstein condensates (BECs) of Na-23 atoms, creating a pure F = 1 BEC of approximately 1.1 x 10^5 sodium atoms with a fast forced evaporation process. The system reliably generates the condensate at a rate exceeding 10^5 atoms every approximately 8 seconds. Additionally, the lifetimes of the mixed F = 1 condensate and the spin components (m ( F ) = 0, m ( F ) = +1) were compared.
