Generation of 0.5 W of cw orange laser radiation at 590-nm by single-pass frequency doubling of 1180-nm high-power Raman-shifted Yb-doped fiber laser in a 20-mm long periodically poled MgO doped lithium niobate (PP-MgO:LN) crystal with internal frequency doubling efficiency of 3.3% is presented. At the low-power level where the laser linewidth was close to the acceptance bandwidth of the PP-MgO:LN crystal, frequency doubling efficiency of 1.36%/W was obtained.
