Improved understanding of the interaction of radiation with cold atomic vapors and BEC's will be sought, using nonlinear spectroscopy (both continuous wave and pulsed). In cw spectroscopy collisional effects in cold vapors and mean field shifts and scattering in BECs will be studied as a function of the frequency difference between two fields. The spectrum of recoil-induced resonances will be calculated. For pulsed field interactions both the impulse and Bragg scattering limits will be studied.

我们将利用非线性光谱学（包括连续波和脉冲），寻求对辐射与冷原子蒸气和BEC相互作用的更好理解。 在连续波光谱中，冷蒸气中的碰撞效应和玻色-爱因斯坦凝聚体中的平均场位移和散射将作为两个场之间频率差的函数进行研究。 将计算反冲诱导共振的频谱。 对于脉冲场的相互作用，脉冲和布拉格散射的限制将进行研究。
