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 heal-spreading devices which
have a thermal contact with each second face in order So remove beat from the active element.
