title = "Generation of 9.3-W multimode and 4-W single-mode output from 7-cm short fiber lasers",
abstract = "We generate 9.3-W continuous-wave 1535-nm multimode output from a 7.0-cm short-length Er-Yb codoped phosphate fiber laser. A slope efficiency of 29% is obtained at pump powers below 27 W. Very high output power per unit fiber length of 1.33 W/cm is achieved. From another 7.1-cm Er-Yb codoped fiber laser, 4.0-W single-transverse-mode output with M 2 ≈ 1.1 is generated.",

Measured (symbols) and calculated (lines) output signal powers and residual pump powers of the 7.0-cm multimode fiber laser. Filled squares and solid line are for the 1535-nm signal from the laser using an R ( ) 30% output mirror. Filled circles and dashed line are for the 1535-nm signal from the laser without an output mirror. Empty circles and dotted line are for the residual 976-nm pump light that exits the laser in the absence of an output mirror. Inset is a picture of the D-shaped fiber end facet of this laser.",
