Abstract

New type of solid-state laser for several kilowatts is discussed. The main difficulty for the high power solid-state laser is the thermal effects induced in the solid gain medium by the pumping light. As one of solutions to this problem, an annular type of solid gain medium is proposed and its thermal characteristcs are discussed on a concrete example. It is shown that the thermal stress can be drastically redusced by using the annular type of gain medium and that a laser with this annular gain medium is easily scalable to any high power. Several kinds of resonators are considered for the annular type of solid gain medium.
