Since the invention of the slab-geometry solid-state laser in 1972, 1, this geometry has been proven to be more suited for high average power operation.2,3 The zigzag configuration eliminates the thermal induced beam distortions and increases the average power capability. The moving-slab laser was first proposed by Kane and Byer for the low thermal conductivity Nd:glasses. By moving a piece of glass medium, it is possible to spread the thermal load over a large area while maintaining high gain in the small volume pumped by the lamps. A hollow cylinder of Nd:glass rotating around its axis, which can realize uniform rotating simply, overcomes the disadvantage of the non-uniform motion of moving-slab at the turning points. In this paper, we give theoretical analysis of thermal effects in rotating hollow cylinder lasers and some useful performance scaling relations for guiding our initial design.
