Abstract:
We present a new apparatus making possible both homogeneity and multipass pumping. It is made up of a square section kaleidoscope made of transparent medium on the terminal faces of which are set mirrors with transparent holes at the centers. The kaleidoscope homogenizes the beam. The pump power reflected by the amplifier medium returns in the kaleidoscope, and the mirrors reflect this pump light toward the amplifier medium.
