摘要	PURPOSE:To implement compact configuration, high efficiency and a long life, by constituting the active part of a semiconductor crystal by a single quantum well structure and a single epitaxial crystal, whose band width changes on both sides and which has the same or similar lattice constant throughout the entire body. CONSTITUTION:On a CdS crystal substrate 1, a ZnCdSSe mixed crystal layer 2, in which lattices are approximately aligned, is formed. The composition of the layer is monotonously changed in a linear or curved shape so that the narrowest band width is obtained at an active region 3 at the central part. Similar mixed crystal layer 4 and CdS layer 5 are formed in a vertically symmetrical pattern. Pumping light 6 is directly converged by a light source or once converged into a single mode optical fiber 7, and then the light is inputted to the side surface. For effective laser oscillation, dichroic optical fiber 8, which can transmit the pumping light and is reflective against the oscillating light is attached to the input side of the pumping light; and a dichroic optical film 9 which is reflective against the pumping light and partially transmissive for the oscillating light, is attached to the output side.
其他摘要	用途：通过单量子阱结构和单个外延晶体构成半导体晶体的有源部分，实现紧凑的结构，高效率和长寿命，其带宽在两侧变化并具有相同或相似的晶格贯穿整个身体。组成：在CdS晶体衬底1上，形成ZnCdSSe混晶层2，其中晶格近似对齐。该层的组成以线性或弯曲的形状单调变化，从而在中心部分的有源区3处获得最窄的带宽。类似的混晶层4和CdS层5以垂直对称的图案形成。泵浦光6直接由光源会聚或者一旦会聚成单模光纤7，然后光被输入到侧面。为了有效的激光振荡，可以传输泵浦光并且反射振荡光的二向色光纤8连接到泵浦光的输入侧;并且，二向色光学膜9附着在输出侧，该二向色光学膜9反射泵浦光并且对于振荡光是部分透射的。
