MODULE OF A SOLID-STATE PLATELET LIGHT-PUMPED LASER

摘要

The inventive module of a light-pumped laser comprises light pump sources, a solid-state active element which is embodied in the form of a plate and provided with a couple of first opposite side faces, the distance therebetween defining the width of the active element for passing a pump radiation therethrough from the pump sources to the active element; a couple of second opposite side faces, the distance therebetween defining the thickness of the active element, which faces are embodied in the plane-parallel manner in order to direct a beam of formed laser radiation in such a way that it enables said beam to pass along the length of the active element in a zigzag manner, undergoing a total internal reflection from the couple of second side faces; a couple of end faces, the distance therebetween defining the length of the active element, and also heat-spreading devices which have a thermal contact with each second face in order to remove heat from the active element. <IMAGE>
