Description

双色激光同光路系统
技术领域
本发明涉及激光应用领域，具体指通过电路控制实现双色激光同光路输出。
背景技术
随着现在科技的不断发展，激光器应用也日益增长，尤其是双色激光同光路输出，目前常用的双色激光同轴方法是采用PBS（偏振分束棱镜）或者光纤合束实现双色激光同光路。这两种方法有两个缺点：一是结构复杂不好调节，二是体积较大。
发明内容
为了解决上述问题，本发明双色激光同光路输出，结构紧凑，调节方便。
本发明的技术方案是：一种实现双色激光同光路的系统，其特征在于：包括LD泵浦源、激光晶体和透镜，两个激光晶体和透镜依次同光轴设置，两个LD泵浦源分别垂直放置于每一激光晶体的下方，两个激光晶体分别镀不同的膜系，通过膜系控制发射不同波长；通过电路控制（LD泵浦源）实现双色激光同光路输出。
两个激光晶体同时发射双色激光或只有一个激光晶体发射一束激光。
所述的激光晶体的端面镀膜构成谐振腔，或在激光晶体的两端加反射镜构成谐振腔。
所述的LD泵浦源的工作方式设置为连续LD或者脉冲LD，形状设置为环形泵浦、一个LD泵浦或者多个LD泵浦。
本发明的优点是：结构紧凑，调节方便。
附图说明
图1为本发明一个实施例（激光晶体镀膜）的结构示意图；
图2为本发明另一个实施例（激光晶体两端加反射镜）的结构示意图；
附图标记说明：1、2-LD泵浦源，3、4-激光晶体，5-整形透镜，6、7、8-反射镜。
具体实施方式
下面结合附图对本发明的双色激光同光路系统进一步详细的说明。
实施例1：
结构如附图1，是简化的光路示意图，双色激光同光路输出有以下几部分构成：两个激光晶体3和4、两个泵浦源以及整形透镜5，泵浦源1和2为LD（Laser Diode）。其中两个LD泵浦源1和2分别垂直放置于两个激光晶体3和4的下方，两块晶体3和4分别镀不同的膜系，通过膜系控制发射不同波长，且两块晶体3和4与整形透镜5依次同轴设置，激光晶体3和4的两端面镀不同的膜系构成两个谐振腔，通过电控制LD泵浦晶体，实现同时发射激光或者只允许其中一个发射激光。
实施例2：
结构如附图2，本实施例和实施例1的区别在于，本实施例的LD泵浦源换为脉冲LD，用3个平面高反镜6-8作为腔镜。同样两个脉冲LD垂直放置于激光晶体下方，两块激光晶体各自两端由反射镜构成腔镜，其中中间的一个反射镜7是共用的，双色激光的发射方式以及发射脉宽通过电控制实现。
