Description

负极板两端支撑在平行支架上的射频激光器 技术领域
本发明涉及射频激光器，具体涉及负极板两端支撑在平行支架上的射频激光器。
背景技术
目前市场上存在的传统的射频激光器都是负极板一端固定在全反法兰上，负极板另一端固定一销轴后直接插入半反法兰的一孔中。
该类射频激光器主要存在以下缺陷：
(1)安装困难，
(2)安装精度低，
(3)安装后内部产生的相对应力无法消除，
(4)激光器调节困难且稳定性差，
(5)光电转换效率低，
(6)激光器寿命短。
发明内容
鉴于上述背景情况，本发明提供一种负极板两端支撑在平行支架上的射频激光器。
根据本发明的一方面，提供一种负极板两端支撑在平行支架上的射频激光器
优选地，负极板两端支撑在平行支架上的射频激光器，其负极板是支撑在两平行支架上的。
优选地，负极板两端支撑在平行支架上的射频激光器，两平行支架固定在激光器壳体上。
优选地，负极板两端支撑在平行支架上的射频激光器，：两平行支架的中间颈部厚度不同。
优选地，负极板两端支撑在平行支架上的射频激光器，其一平 行支架的颈部厚度较厚。
优选地，负极板两端支撑在平行支架上的射频激光器，其二平行支架的颈部厚度较窄。
优选地，负极板两端支撑在平行支架上的射频激光器，两平行支架有其一在激光器轴向上有弹性自由度。
优选地，负极板两端支撑在平行支架上的射频激光器，两平行支架的高度是相等的。
优选地，负极板两端支撑在平行支架上的射频激光器，其固定平行支架和负极板的螺纹孔都是盲孔。
与传统的射频激光器相比，负极板两端支撑在平行支架上的射频激光器具有以下优点：(1)安装方便，(2)安装精度高，(3)对激光器装配无影响，(4)光电转换效率高，(5)激光器寿命长。
附图说明
结合以下附图来详细描述本发明的示例实施例，附图中：
图1示出了根据本发明的示例实施例的负极板两端支撑在平行支架上的射频激光器的剖视图
图2示出了根据本发明的示例实施例的平行支架颈部较窄的轴测图；
图3示出了根据本发明的示例实施例的平行支架颈部较宽的轴测图
具体实施方式
以下结合附图来详细描述本发明的示例实施例的负极板两端支撑在平行支架上的射频激光器。
如图1所示，根据本发明的示例实施例的负极板两端支撑在平行支架上的射频激光器，主要由激光器壳体16、平行支架1、平行支架2、负极板7、正极板8、等离子区9、射频电极10、全反法兰11、半反法兰12、全反射镜13、半反射镜14、激光输出窗等组成。
如图1所示，平行支架1和平行支架2由固定螺丝3、5分别固定在了射频激光器的壳体16上，负极板7固定在平行支架1和 平行支架2上，由固定螺丝4、6由下向上固定。
如图1、2所示，平行支架1的中间颈部较窄，在1到2毫米之间，具有一定量的弹性变量，当负极板7在激光器轴向上热胀冷缩时，其变量将由平行支架1在激光器轴向是给于弥消，负极板7在激光器径向上因其板宽较小，其变量接近于零，忽略不计。故平行支架1即做固定用，又起弥消负极板变量之用。
如图1、3所示，平行支架2中间颈部较宽，弹性变量接近于零，故平行支架2只做固定端。
以上对本发明的示例实施例的详细描述是为了说明和描述的目的而提供。不是为了穷尽或将本实用新型限制为所公开的精确形式。显然，许多变型和改变对本领域技术人员而言是显而易见的。实施例的选择和描述是为了最佳地说明本发明的原理及其实际应用，从而使本领域其他技术人员能够理解本发明的各种实施例和适于特定使用预期的各种变型。本发明的实施例可以省略上述技术特征中的一些技术特征，仅解决现有技术中存在的部分技术问题。而且，所公开的技术特征可以进行任意组合。本发明的范围由所附权利要求及其等价物来限定，本领域技术其他人员可以对所附权利要求中所公开的技术方案进行各种变型和组合。
