980nm与2790nm铒激光双波长治疗仪
摘要：
本发明公开了一种980nm与2790nm铒激光双波长治疗仪。它的输出波长为532nm的激光器的光路上依次置有第一45゜角反射镜(M1)、非球面透镜(M4)和光纤，非球面透镜(M4)的焦距为15～25mm，其双面均镀有532nm、980nm和2790nm的增透膜；输出波长为980nm的激光器的光路上依次置有第二45゜角反射镜(M2)、第一45゜角反射镜(M1)、非球面透镜(M4)和光纤；输出波长为2790nm的铒激光器的光路上依次置有第三45゜角反射镜(M3)、第二45゜角反射镜(M2)、第一45゜角反射镜(M1)、非球面透镜(M4)和光纤。它既进一步地拓展了铒激光治疗仪的适用范围，又有着结构简单、装调便捷的优点，还由单一光纤同光轴输出了包含指示光的三种激光，可精确地用于粉碎和治疗人体的病变组织。
摘要（英）：

The invention discloses a 980nm and 2790nm erbium laser double-wavelength therapeutic apparatus. A first 45-degree mirror (M1), an aspheric lens (M4) and an optical fiber are sequentially arranged on the light path of a laser with the output wavelength being 532nm. The focal length of the aspheric lens (M4) is 15-25mm, and both sides are coated with 532mm, 980mm and 2790mm antireflection films. A second 45-degree mirror (M2), the first 45-degree mirror (M1), the aspheric lens (M4) and the optical fiber are sequentially arranged on the light path of a laser with the output wavelength being 980nm. A third 45-degree mirror (M3), the second 45-degree mirror (M2), the first 45-degree mirror (M1), the aspheric lens (M4) and the optical fiber are sequentially arranged on the light path of an erbium laser with the output wavelength being 2790nm. The scope of application of the erbium laser therapeutic apparatus is further expanded, and the therapeutic apparatus has the advantages of simple structure and convenient assembly and adjustment. Three kinds of laser light including indication light are output by a single optical fiber through the same optical axis. The therapeutic apparatus can be accurately used to crush and treat diseased tissues of the body.
