A magneto-optical trap (MOT) for cesium atoms that operates without a separate repumping laser is reported. The differences between a normal MOT and this kind of MOT have been experimentally studied. The influences of a repumping laser on cooling and trapping cesium atoms in the MOT have been carefully investigated. The results reveal that it is the critical injection-locked state of the diode laser that makes magneto-optical trapping of cesium atoms possible without a separate repumping laser.

Laser cooling and trapping o f cesium atoms using an indigenously developed magneto-optieal trap is reported.The experimental set up o f the trap and laser-cooling procedure adapted for eooling o f cesium atoms is discussed.
