Patent ID: 8320426

Claim:
An apparatus for selectively distributing energy from at least one laser beam comprising: a housing extending along a longitudinal axis and having axially spaced front and rear sides and opposing axially extending sides; an elongated sealed chamber defining a beam cavity within the housing, and limited between opposing portions of respective front and rear sides of the housing and a pair of elongated side walls, the side walls bridging the opposing portions of respective front and rear sides and spaced radially inwards from the opposing axially extending sides of the housing; at least one input port axially extending through the portion of the front side of the housing and opening into the beam cavity; at least one output port being provided on one of the opposing sides and extending so as to open into the beam cavity; at least one control port mounted on the other of the opposing sides opposite the at least one output port, the control port including a mirror disposed within the beam cavity, wherein the mirror is movable between a first in-beam position to direct the at least one laser beam, entering the cavity through at least one input port, to the at least one output port, and a second out-of-beam position wherein the laser energy is unaffected by the mirror allowing the laser beam to axially propagate towards the rear side of the housing, and a motor mounted in the housing outside the cavity and operative to control the position of the mirror.
