Abstract
Pumping laser diodes (3) are disposed around a reflector tube (2) having narrow windows (14) through which the emitting areas of the diodes look. The tube leaves an angular gap (16) around a rod to be pumped (1) and a cooling liquid flows in said gap. The invention is particularly applicable to optically pumping a YAG rod.
