Abstract
A diode-laser-array end-pumped efficient CW Nd:GdVO4 laser at 1.06 mu m has been developed. A low-order-mode output power of 14.3 W was obtained at th e maximum available pump power of 26 W, giving an optical conversion effici ency of 55% and an average slope efficiency of 62%. The laser output beam q uality factor at full pump power was determined to be M-2 < 1.8. It is also shown that only lightly doped Nd:GdVO4 crystals are suitable for high-powe r end-pumped lasers.
