We present the experimental results of a 1083 nm fiber amplifier tandem pumped by 1030 nm fiber laser. The output characteristics of the tandem pumped amplifier with cladding-pump and core-pump schemes are both investigated. The 1083 nm signal laser has not been efficiently amplified when cladding-pumped by 1030 nm laser for the weak absorption of the gain fiber. The core-pump scheme works well with the amplifier. The output properties with different gain fiber length are experimentally investigated. The maximum output power is 2.4 W with power conversion efficiency of 60%.
► All-fiberized, tandem-pumped fiber amplifier with double-clad YDF is experimentally investigated for the first time. ► Both core-pump and cladding pump scheme are attempted. ► The 1083 nm signal laser is effectively amplified when core pumped by 1030 nm fiber laser.
