| 摘 要： | A highly efficient cascaded P-doped Raman fiber laser(RFL)pumped by a 1064-nm continuous wave (CW)Nd:YVO_4 solid-state laser is reported.1.15-W CW output power at 1484 nm is obtained while the input pump power is 4 W,corresponding to the power conversion efficiency of 28.8%.The threshold pump power for the second-order Stokes radiation is 1.13 W.The slope efficiency is as high as 42.6%.The experimental results are in good agreement with theoretical ones.Furthermore,the power instability of the P-doped RFL at 1484 nm in an hour is observed to be less than 5%.
