如图2所示为本发明的一种激光光源***结构示意图，包括：可产生蓝色激光的光源激发单元20、色轮10、反射镜组、色镜组、红色滤光片40和光束调整单元60。
其中反射镜组包括：均可反射所有色光第一反射镜32、第二反射镜34和第三反射镜37。
其中色镜组包括：反蓝光透黄光和绿光的第一色镜31、反绿光透蓝光的第二色镜33、反红光透蓝光和绿光的第三色镜35和反绿光透黄光的第四色镜36。
第一反射镜32、第二反射镜34、第三色镜35和第三反射镜37围成一个矩形，且分别位于矩形的四个顶点位置，第二色镜33设置于第一反射镜32和第二反射镜34之间，第一色镜31设置于第一反射镜32和第三反射镜37之间，第四色镜36设置于第三反射镜37和第三色镜35之间，红色滤光片40设置于第四色镜36和第三色镜35之间，光束调整单元60设置于色轮10和第四色镜36之间，色轮10设置于第一色镜31和第一反射镜32之间，且第一色镜31反射的蓝光投射至色轮10的外圈，第四色镜36反射的绿光经光束调整单元60投射至色轮10的内圈。
光源激发单元20发出蓝光，经第一色镜31反射至色轮10的外圈，当蓝光接触色轮10外圈的蓝光透光区时，透过色轮10到达第一反射镜32，经反射到达第二色镜33，透射到达第二反射镜34并反射至第三色镜35，透射出光源***；当蓝光接触色轮10外圈的黄光色荧光区时产生黄光并反射，当蓝光接触色轮10外圈的绿色荧光区时产生绿光并反射，反射出的黄光和绿光透射第一色镜31，经第三反射镜37反射至第四色镜36，第四色镜36将绿光反射至光束调整单元60，将黄光透射至红色滤光片40。
到达光束调整单元60的绿光根据光源***的结构大小需求来选择采用准直透镜组或者聚光透镜组，当光源***要求结构紧凑时选择聚光透镜组，来减小光束的角度，从而减小色轮10的面积；当光源***要求较高的光亮效果且空间充足时选用准直透镜组，来获取更好的光亮效果。绿光经过光束调整单元60后到达色轮10的内圈绿光透光区，经第二色镜33、第二反射镜34反射至第三色镜35，并透射出光源***。
到达红色滤光片40的黄光，经过红色滤光片40滤出红光，红光经第三色镜35反射出光源***。从而实现整个光源***依次输出蓝光、绿光和 红光三基色。
