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.
