CN206195150U 一种多个二极管激光器列阵封装结构 有权

一种多个二极管激光器列阵封装结构
摘要：
本实用新型为一种多个二极管激光器列阵封装结构，N个二极管激光器及其非球面准直透镜一一嵌于金属热沉的N个安装孔内，柱面透镜位于各孔顶面，与一套二极管激光器和非球面准直透镜相对，构成激光发射光学单体。热沉的一个安装孔处于中心，其余安装孔呈中心对称分布。处于外周的各柱面透镜为径向或周向安置。二极管激光器经粘胶与孔壁固连，其管脚经安装孔底部与电源线连接。每个安装孔孔缘两侧的一对夹持片柱面透镜卡在热沉顶面一对夹持片之间粘结固定。本封装结构输出功率是N个二极管激光器功率之和，保证多个激光发射光学单体的组合具有小的发散角与平行度；冷却装置简单，激光传输效率高、体积小，封装工艺简单。
摘要（英）：

The utility model relates to a plurality of diode laser array packaging structure, a N diode laser and aspheric surface collimating lens inlay one by one in the N of a metal heat sink mounting hole, and cylindrical lens is located each hole top surface, and is relative with aspheric surface collimating lens with one set of diode laser, constitute laser emission optics monomer. A heat sink mounting hole is in the center, and all the other mounting holes are central symmetry and distribute. Each cylindrical lens who is in the periphery is radial or the circumference arrangement. Diode laser links firmly through viscose and pore wall, and its pin is connected with the power cord bottom the mounting hole. A pair of holding piece cylindrical lens card of every mounting hole peritreme both sides bonds fixedly between a pair of holding piece of heat sink top surface. This packaging structure output is a N diode laser power sum, guarantees that the free combination of a plurality of laser emission optics has the little angle of divergence and the depth of parallelism, cooling device is simple, and laser transmission is efficient, small, and packaging technology is simple.
