摘　　要：基于经典的原理，并运用巧妙的构思，设计出一种新型的连续可调的激光衰减器，取得了满意的效果。它能连续地改变激光束的功率或能量，同时不影响激光束的其它特性，满足了激光空域参数测量的需要。Abstract Based on the classical theories, a novel continuously adjustable laser attenuator has been developed. It can continuously change the power or energy of the laser beam without any effects on the other properties of the laser, thus, meets the requirements for measurements of the space domain parameters of laser.
