摘要： The present invention relates to a solid state laser generation apparatus which is composed of modularized solid state lasing units which enable construction of a compact cascading laser apparatus having a low lasing threshold value and a high laser generation efficiency. A lasing rod and the electrodes for the excitation of the rod are housed in a common module casing which has depressed sections on its external surface. When assembling two modular units, one of the module units is rotated axially with respect to the other in such a way to insert the electrodes into the depressed section on the external surface of the neighboring module so as to minimize the mechanical interference caused by the neighboring components. By utilizing such a modular arrangement, the lasing rod spacing between the neighboring module units can be shortened, thus resulting in lower coupling losses between the adjacent rods even during the initial phase of the operation. The resulting multi-rod laser apparatus, whose input/output power relationship is linear, is efficient and compact, thus allowing an improved control over the laser output power and facilitating the overall operation.
