ABSTRACT:
Two identical prism telescopes each comprised of a train of right angle prisms are used to spread out a laser beam to the maximum width of an acousto-optic cell and reconverge the beam to original dimensions. The first telescope increases the beam size along one dimension while bending the beam through 90.degree.. The second telescope reduces the beam size and multiplies the angle of deflection while redirecting the beam through another 90.degree.. There is a 180.degree. fold in optical path and this configuration is compact, has low losses, and is easy to mount and align.
