  Manipulation of the quantum state by the Majorana transition in spinor BEC
system has been realized by altering the rotation frequency of the magnetic
field's direction. This kind of manipulation method has no limitation on the
transition speed in principle and the system is well closed, which provides a
new and superior tool to manipulate quantum states. Using this methord on
pulsed atom laser, multicomponent spinor atom laser is generated. We
demonstrate that the experiment results are agreed with the theoretical
predication.
