| Abstract: | Using the time-dependent multilevel approach(TDMA), we have calculated the coherent population transfer among the quantum states of potassium atom by a single frequency-chirped laser pulses.The result shows that the population can be transferred to a target state and be trapped there by changing the parameters of the laser pulse. |
