Calculation results reveal that the equivalent beam length is more suitable to describe the beam size of vortex beam after propagation.

数值计算进一步说明，等效光斑尺寸更适合用来表征涡旋光束传输后的光斑大小。

The coupling among laser modes and the relations between equivalent beam spread Angle and the surface deformation of the mirrors are obtained.

给出了激光模式之间的耦合以及等效光束发散角与镜面变形量之间的关系。

Too diffuse a beam, and they would miss each other by the subatomic equivalent of a mile.

Because the beam is being so precisely targeted, a bigger dose can be given, equivalent to several sessions all at once.
