基于红绿蓝(RGB)三基色直接半导体激光器合成的白激光光源具有转换效率高、显色指数好、输出功率高等优点，是新一代的理想照明光源和显示光源之一。基于RGB三基色半导体激光器件，通过空间合束、波长合束等，三基色光耦合进单光纤，光纤输出合束光功率超过100 W。根据色度学原理进行颜色功率配比，获得了功率达63 W、色温为5 710 K的白光输出，与标准白光D65相比色温偏差小于12.2%。在此基础上，调整红色激光输出功率，获得了功率达58.4 W、色温为6 480 K的白光输出，与标准白光D65相比色温偏差小于3.08%。基于该光源，通过调整激光功率配比，可实现不同色温的合束激光输出。

The white laser light source synthesized by red, green and blue(RGB) direct semiconductor laser has the advantages of high conversion efficiency, good color rendering index and high output power. It is one of the new generation ideal lighting source and display source. Based on the RGB three-color diode laser devices, through the space beam combining and wavelength beam combining, the RBG lights are coupling into a single optical fiber, optical fiber output beam power more than 100 W. The power ratio of different colors is carried out according to the colorimetry principle. The white light with a power of 63 W and a color temperature of 5 710 K ,which is less than 12.2% compared with the standard white light D65 was obtained. On this basis, by adjusting the output power of the red laser, a white light output with a power of 58.4 W and a color temperature of 6 480 K was gotten. Compared with standard white light D65, the deviation of color temperature was less than 3.08%. The light source based on this structure can achieve different display effects by adjusting the laser power ratio.
