In our experiment a weak laser beam, with a frequency of 1.7 GHz red-detuned from the sodium 3S1/2 F = 1 → 3P3/2 F = 0, 1, 2 transition, was split into two beams in order to form the two Bragg beams [4, 12]. The beams were sent through two acousto-optical modulators driv ...

Design study of a Magneto-Optical Trap for laser cooling of rubidium
... γ/2 causes an increased absorption from both lasers for atoms with almost zero speed. These absorptions cause heating. The value of the Doppler limit does not differ much between the two isotopes, vd =12 cm/s and Td = 140µK, is valid for both [1]. It was thought to be lowest reachable temperature wi ...
