摘　　要：在多模掺镱双包层光纤上,利用相位掩模法直接写制Bragg光栅作为激光器后腔镜,得到多波长激光输出.在室温下,通过调节偏振控制器可以得到稳定的单波长及多波长的激光输出,输出波长范围在1056～1061nm,线宽均小于0.02nm.在25W的976nm激光泵浦下,激光器得到功率为6W的多波长输出.A switchable multi-wavelength double-clad fiber laser was demonstrated. Using a phase mask,the fiber Bragg gratings directly in a multimode double-clad Yb^3＋-doped fiber were fabricated as the frequency selective mirror. The single-dual-triple- and four wavelengths output respectively through adjusting the polarization controller were obtained. The wavelength is between 1 056 nm to 1 060 nm and linewidth is less than 0.1 nm. Under a 25 W pump power of 976 nm laser, the maximum output power of the laser is above 6 W in multi-wavelength.
