    • A semiconductor laser includes a multilayer semiconductor laser heterostructure including at least one active layer of a II-VI semiconductor material and is optically pumped by one or more indium gallium nitride (InGaN) diode-lasers. Group II elements in the II-VI semiconductor material are zinc, cadmium, magnesium, beryllium, strontium, and barium. Group VI elements in the II-VI semiconductor material are Sulfur, Selenium, and Tellurium. In one example of the laser an edge emitting heterostructure includes two active layers of zinc cadmium selenide, two waveguide layers of zinc magnesium sulfoselenide, and two cladding layers, also of zinc magnesium sulfoselenide. Proportions of elements in the cladding layer material and the waveguide layer material are selected such that the waveguide layer material has a higher bandgap than the material of the waveguide layers. In another example, a two dimensional array of InGaN diode-lasers is arranged to optically pump a one dimensional array of II-VI edge-emitting heterostructure lasers.
    • 半导体激光器包括包含至少一个II-VI半导体材料的有源层的多层半导体激光异质结构,并被一个或多个铟镓氮(InGaN)二极管激光器光泵浦。 II-VI族半导体材料中的II族元素是锌,镉,镁,铍,锶和钡。 II-VI族半导体材料中的VI族元素是硫,硒和碲。 在激光器的一个实例中,边缘发射异质结构包括两个硒化锌镉活性层,两个磺酸锌镁纳米波导层和两个包层,也是锌硫酸镁镁。 选择包层材料和波导层材料中的元素的比例使得波导层材料具有比波导层的材料更高的带隙。 在另一个示例中,布置了InGaN二极管激光器的二维阵列以光学泵浦II-VI边缘发射异质结构激光器的一维阵列。
