Abstract
Prism beam expansion system which having two or more right angle prisms with the same structure. The incident light beam enters via an incident inclined plane and exits as an exit light beam that is perpendicular to an exit right angle plane of the same right angle prism. The vertex angle α of all the right angle prisms are the same and satisfies the expression where n1 and n2 represent the refractive indexes of the laser beam respectively in the incident media and in the right angle prism.
