Popis: Novel principles of design of a diode-pumped solid-state laser with scalable average output power are described. The approach is based on a double waveguide slab (DWS) concept, when laser slab has a waveguide equality both for pump and laser radiation propagation in the orthogonal directions. The advantages of such a scheme are efficient conduction- cooling and scalability of a laser head to the kW range with the high quality of a laser beam. The feasibility of this concept was proved with the model of a DWS Nd:YAG laser at the level of average output power of 10W. The promising possibility to use thermally strengthened Nd-glass for a high average power qcw laser is discussed.
