摘　　要：It is critical to realize woven and wearable red-green-blue(RGB) whispering gallery mode(WGM)lasing that is tunable and flexible in the fiber braiding cavity. However, it is still a challenge to achieve tunable full-color lasing with the large color gamut by a facile approach. Here, we design the braiding cavity to realize RGB WGM lasing with high performance. The braiding cavity consists of three optical fibers coated with dye-doped polymer. Each fiber therein serves as a resonant cavity to support multiple lasing modes. There is no interference owing to the air gap between them;therefore, we can achieve full-color WGM lasing. The lasing emission in our fiber braiding cavity covers a color gamut of 86.7% larger than standard RGB space.Our work may provide a platform for potential applications in white laser and integrated optoelectronic devices.
