Adjustable High-Energy Soliton Fiber Laser Based on a Spatial Alignment Structure

We demonstrate a self-starting high-energy erbium-doped soliton fiber laser by utilizing a spatial alignment structure (SAS). The saturable absorption (SA) effect of the SAS is based on the nonlinear coupling efficiency variation. Stable solitons can exist in the 400 mW-1.5 W pump power range. The c...
