WebRayleigh Range (ZR) is the distance from the beam waist where the beam radius has increased 1.414 times its initial value. This is the point at which the area of cross-section is doubled. If we focus a laser beam, at the focal point, theoretically the intensity goes to infinity. But this is practically not possible because a laser beam cannot ... 在光學及雷射科學中，瑞利距离或瑞利长度（Rayleigh length）或瑞利範圍（Rayleigh range）是指光束沿著其行進方向，從其腰部到其面积為腰部面积兩倍的截面的距離，此时截面半径约为倍的腰部半径。另一個相關的參數為共焦參數（confocal parameter）b，恰為瑞利距离的兩倍。當用高斯光束來做為光束模型時，瑞利距离是相當重要的參數。 list of hotels in portland maine
