Paper Abstract

The output characteristics of double cladding fiber laser are investigated pumped by 915nm and 975nm diode lasers. The average effective absorption coefficients for two kinds pump wavelengths are given. A 20W Ytterbium - doped fiber laser in 1110nm region with near diffraction limited beam spread angle are reported.
