Abstract: An optical package includes a beam combiner that combines laser light from a laser unit into a single laser beam, a movable mirror apparatus, and a fixed folding mirror which reflects the single laser beam toward the movable mirror apparatus. Beam equalizer optics cause increase of a slow axis divergence rate of the single laser beam such that its slow axis divergence rate is equal to its fast axis divergence rate. The movable mirror apparatus directs the single laser beam through an exit window. The beam equalizer optics include at least one negative spherical lens shaped such that a slow axis divergence rate of incident light is increased but a fast axis divergence rate of incident light is unaltered.
