Abstract A reflecting device having a housing with a fixed body and a second movable body mounted thereon, each body having a reflecting passage means extending therethrough with each passage having an axis. Said second movable body being mounted so that the axes of each passage means can be aligned and the distance between the fixed body and movable body can be controlled. Each reflecting passage has a small diameter opening and a large diameter opening intersecting the sides of its respective body. In their mounted position the small diameter openings face each other. The surface of the reflecting passage means of said second movable body being formed so that an input beam entering the large diameter opening will have the rays of the beam focused so as to pass through the small diameter opening and have the focal point lie outside the first passage. The surface of said reflecting passage means of said first body being formed as a reflecting surface so that the beam leaving the focal point will have the rays deflected to form a collimated beam of a different diameter than that of the input beam. When this device is used as an aerodynamic window in a gas dynamic laser, the output beam can be of the same diameter as the input beam.
A reflecting device for a beam includes: a. a housing, b. a first body fixed on said housing, c. a second body mounted on said housing adjacent to said first body, d. said first body having a first passage therethrough, e. said first passage having a small diameter opening intersecting one surface of said first body and a large diameter opening intersecting another surface, f. said second body having a second passage therethrough, g. said second passage having a small diameter opening intersecting one surface of said second body and a large diameter opening intersecting another surface, h. the surface of one of said passages being formed as a first reflecting surface so that an input beam entering the large diameter opEning will have the rays of the beam focused so as to pass through the small diameter opening and have the focal point lie outside the one passage, i. said first and second body being positioned adjacent each other with the small diameter openings facing each other, j. each of said passages having an axis, k. means for aligning said axes, l. the surface of the other passage being formed as a second reflecting surface so that the beam leaving the focal point will have the rays deflected to form a desired output beam, m. means for moving said first body in relation to said second body along said axes to control the position of the focal points of the first and second reflecting surfaces.
