We demonstrate enhanced loading of a vapor-cell magneto-optical trap f
or sodium atoms operating on a combination of atomic transitions, know
n in the literature as type I tuning, by using a second, nonoverlappin
g laser beam that captures atoms through a different combination of tr
ansitions (type II tuning). This two-color trap configuration has allo
wed us to achieve an similar to 10-fold improvement in the number and
density of trapped atoms. (C) 1995 Optical Society of America
