Fiber coiling method, fiber laser, and fiber amplifier

The invention provides a fiber coiling method, a fiber laser, and a fiber amplifier. The fiber coiling method includes the steps: according to the fiber diameter, determining the minimum radius for fiber coiling, and according to the demand for the light beam quality level, determining the maximum radius for fiber coiling; and according to the determined minimum radius and maximum radius, performing fiber coiling. The fiber coiling method can reduce the macrobend loss of laser in the fiber, can reduce generation of high order mode in the fiber, can improve the light beam quality, and can solvethe problem that a traditional coiling method can certainly cause fiber flying (fiber flying means that an inner ring fiber end head is cocked to connect with other components). On the basis of the fiber coiling method, the invention also provides a fiber laser and a fiber amplifier. 本发明提供了种光纤盘绕方法及光纤激光器和光纤放大器。所述光纤盘绕方法具体为：根据光纤直径确定光纤盘绕的最小半径，根据对光束质量高低的要求确定光纤盘绕的最大半径；根据上述确定的最小半径和最大半径，进行光纤盘绕。所述光纤盘绕方法可以减轻激光在光纤中的宏弯损耗，可以降低光纤中高阶模的
