本公开涉及具有多个泵浦激光器的掺铒光纤放大器。一种在光纤中进行放大的方法，包括：通过一个或多个泵浦激光器在光纤的输入端和输出端之间将第一组的一个或多个波长的泵浦激光注入到光纤中；以及通过所述一个或多个泵浦激光器在光纤的输入端和输出端之间将第二组的一个或多个波长的泵浦激光注入到光纤中。注入到光纤中的第一组和第二组的泵浦激光的波长在968nm和982nm之间或1470nm和1490nm之间的范围内彼此不同，并且在光纤中造成反转，并且注入到光纤中的第一组和第二组的泵浦激光的波长不同于所述一个或多个通信波长的激光。 A method of amplification in an optical fiber includes injecting into the optical fiber, by one or more pump lasers, between an input and an output end of the optical fiber, a first set of one or more wavelengths of pump laser light; and injecting into the optical fiber, by the one or more pump lasers, between the input and the output end of the optical fiber, a second set of one or more wavelengths of pump laser light. The wavelengths of the first and second sets of pump laser light injected into the optical fiber are different from each other and create an inversion in the optical fiber, and the wavelengths of the first and second sets of pump laser light injected into the optical fiber are different from the one or more communication wavelengths of laser
