High-power continuous-wave generation at 533 nm is demonstrated in bulk periodically poled KTiOAsO4 (KTA) by single-pass frequency doubling of a VBG-locked Yb-doped fiber laser. Absorption characteristic and second harmonic generation (SHG) performance of different KTA samples are studied and compared. The best performing sample catered for 25%-efficient SHG of 13.6 W green light with high spatial beam quality M2 <1.2.
