We have modelled and used polarization spectroscopy to lock a very compact, high-performance extended cavity diode laser system to the 85Rb (F = 3 to F′ = 4) transition. The laser has a linewidth of 135 kHz. Using this system we have trapped and cooled 1.5×108 Rb atoms in a magneto-optical trap. Atoms remained continuously trapped in the MOT for several minutes.
