原子衍射对集体原子反冲Laser的影响

Effects of atomic diffraction on the Collective Atomic Recoil Laser

M. G. Moore, P. Meystre

摘要:

建立了集体原子反冲激光器的波原子光学理论,对原子质心运动进行了量子力学处理。通过将该理论的预测与经典地处理质心运动的射线原子光学理论的预测进行比较,我们证明,对于一个遥远的情况下-在共振泵浦激光器中,当温度为反冲温度或更低时,射线光学模型不能预测CARL的线性响应,这是由于在这个温度范围内,人们不能再忽略物质波衍射对原子质心运动的影响。

英文摘要:

We formulate a wave atom optics theory of the Collective Atomic Recoil Laser, where the atomic center-of-mass motion is treated quantum mechanically. By comparing the predictions of this theory with those of the ray atom optics theory, which treats the center-of-mass motion classically, we show that for the case of a far off-resonant pump laser the ray optics model fails to predict the linear response of the CARL when the temperature is of the order of the recoil temperature or less. This is due to the fact that in theis temperature regime one can no longer ignore the effects of matter-wave diffraction on the atomic center-of-mass motion.
