چکیده انگلیسی
In this paper, we theoretically demonstrate that the fine green emission in Er3+ ion system can be effectively controlled by the shaped ultra-short laser pulses with a Ï phase modulation. Our results show that the two photon transition probabilities of two excited states are effectively tuned by the single Ï phase modulation of 800Â nm or 1600Â nm laser pulses. By combiningÏ phase modulation of the two exciting pulses, one excited state can be populated at maximum value, while the other state population can be widely tuned from zero to the maximum value. Furthermore, we explain the physical control mechanism of fine green emission by considering the second-order power spectrum of the shaped pulses. These schemes can be applied to realize the selective population of multiple excited states.
