随着生产、科学技术发展的需要,椭圆腔体的应用日益广泛。如在激光技术中,某些固体激光装置的聚光器就采用椭圆腔体。因为它具有聚光效率高,输出功率大的优点。椭圆聚光器按其用途不同,可分单椭圆聚光器、双椭圆聚光器,四椭圆聚光器等类型(图1)。不同类型的椭圆腔体,其加 With the needs of the development of production and science and technology, the application of elliptical cavity is more and more widely. As in laser technology, the condenser of some solid-state laser devices uses elliptical cavities. Because it has the advantages of high light efficiency, output power advantages. Elliptical concentrators according to their different uses, can be divided into single elliptical condenser, double elliptical condenser, four elliptical condenser and other types (Figure 1). Different types of oval cavity, its plus
