强度梯度 meaning in English
intensity gradient
Examples
- Intensity - gradient cooling of atoms in a localized - hollow beam
局域中空光束中原子的强度梯度冷却 - Recent progress in ultrafast optics has allowed the generation of ulfcraintense light pulses comprising merely a few field oscillation cycles . the arising intensity gradient allows electrons to survive in their bound atomic state up to external field strengths many times higher than the binding coulomb field and gives rise to ion - ization rates comparable to the light frequency resulting in a significant extension of the frontiers of nonlinear optics and ( nonrelativistic ) high field physics
随着超快光学技术的发展，仅含几个振荡周期的超强脉冲已经能产生，且其强度梯度可使电子存在比库仑束缚场高许多倍的外场产生的原子束缚态上，并产生了同光频相差不大的电离率，从而促进了非线性光学前沿及非相对论的强场物理的延伸。 - However , the intensity gradient ( force ) of the diffracted light of the semi - gaussian beam is far smaller than that of the evanescent - light wave , so its spontaneous emission probability is greater than that from the evanescent - light one when the normal velo city of the incident atom is greater
然而，因为半束兰失谐高斯光束衍射光场的强度梯度力远小于消逝波光场，所以当入射原子速度较大时，原子在半束兰失谐高斯光束衍射光场中的自发辐射几率要大于消逝波光场。 - Under the same beam parameters , the intensity gradient near the mirror surface of the blue - detune sfgb is the nearly same as that of the sgb , but the intensity distribution of the fgb is a constant within a larger radial range , the width of the sfgb mirror will far greater than one of the sgb mirror
类似地，半束兰失谐平顶高斯光束反射镜和sgb反射镜相比在yoz平面上的衍射强度梯度是近似相同的，也就是说在入射光束参数相同的条件下，在上述二种反射镜表面附近入射原子受到的光偶极排斥力大小是近似相同的。
