Description

一种激光二极管阵列光源模组 A laser diode array source module

技术领域 FIELD

[0001] 本发明涉及激光技术领域,具体涉及一种激光二极管阵列光源模组。 [0001] The present invention relates to the field of laser technology, particularly relates to a laser diode array source module.

背景技术 Background technique

[0002] 激光光源由于其高亮度性、高方向性和高单色性等特性,越来越受到各应用领域的青睐。 [0002] The laser light source due to the nature of its high brightness, high directivity and high color, etc., more and more popular in various applications. 在显示产业方面,诸如电视、投影以及舞台灯等应用领域,大功率、小体积的激光二极管光源的使用越来越普遍。 In the display industry, the application field such as a television, a projection stage lights and the like, high-power, small volume laser diode increasingly common. 然而,由于半导体制造工艺水平及材料本身特性的限制,目前大规模产业化生产的单颗激光二极管的光功率还相对较小:一般蓝光二极管的光功率可做到几瓦的量级,红光激光二极管的光功率也基本可以做到瓦级以上,但是绿光激光二极管的光功率一般也就只有几十到百毫瓦量级的水平,要想获得瓦级的单颗绿光激光二极管还非常困难。 However, due to their own characteristics of the semiconductor material and the level of manufacturing process, the optical power of the laser diode current single large-scale industrial production is relatively small: the optical power of the blue LED may be generally done several watts, red the optical power of the laser diode can be done basically watts or more, but the light power green laser diode generally it was only a few dozen to one hundred milliwatt level, in order to obtain watts of single green laser diode also very difficult. 因此,对于那些需要使用几十上百瓦甚至更高光功率半导体激光光源的应用领域,需要通过特殊的模组设计来满足各种行业需要。 Thus, for those who need to use several tens or even hundreds of watts of optical applications a higher power semiconductor laser light source, it is necessary to meet industry needs a special module design.

[0003]目前业界中在要使用到几十瓦以上的激光光源的场合中,普遍做法是将激光二极管进行阵列排布。 [0003] In the industry to use more than several tens of watts to a laser light source case, the common practice is to be arranged in an array of laser diodes. 在对实际产品中采用的光源模组结构的研究过程中,发现一般使用了激光二极管阵列单面排布,采用面发射激光束的方式代替点发射,获得较高激光能量密度的激光束,另一种常用的方式是采用两个光源模块,每个模块上均有二维排布的激光二极管阵列,采用斜面安装的平面反射镜对其中一个模块发出的光束进行偏转,然后与直面射出的光线进行汇合,利用合光使整个光源模组出射更高能量密度的激光束。 During the study of the structure of a light source module used in the actual product, it was found generally uses a laser diode array sided arrangement, by way of a surface-emitting laser beams instead of the emission point, to obtain a higher energy density of the laser beam of the laser, the other one common way is to use two light source modules, each module has two-dimensionally arrayed laser diode array using a plane mirror mounted on the inclined surface where a light beam emitted by the deflecting module, then the light emitted from face for convergence, using the entire bonding light source module emitted higher energy density of the laser beam. 然而,通过此种方法得到的光源模组发出的激光能量密度还有提升的空间,同时,此种光源模组单元的整体体积较大,将导致后期整机结构尺寸设计时极大地依赖于光源模组的尺寸,使得结构设计出来的整机体积较大,不但影响产品的美观也对实际产品生产工艺带来了不便。 However, the laser energy density there is room for improvement obtained by this method is emitted from the light source module, simultaneously, the overall volume of such a light source module unit is larger, will result in highly dependent on the light source when the late whole structure dimensioned the size of the module, so that the whole structure designed larger, not only affects the appearance of the product but also on the actual production process is inconvenient.
