A polarisation spectrometer locked diode laser for trapping cold atoms
Optics Comm. 170:79–84.
We have modelled and used polarisation spectroscopy to lock
a very compact, high-performance extended cavity diode laser
system to the Rb-85 (F = 3 to F' = 4) transition. The laser
has a linewidth of 135 kHz. Using this system we have trapped
and cooled 1.5 X 10(8) Rb atoms in a magneto-optical trap.
Atoms remained continuously trapped in the MOT for several
minutes. (C) 1999 Elsevier Science B.V. All rights reserved.
