Violet, blue, and green lasers were simultaneously generated by nonlinear processes using ultrafast laser inscribed neodymium‐doped yttrium aluminum borate (Nd:YAl 3 (BO 3 ) 4 or Nd:YAB) channel waveguides under pumping at 815 nm. These visible lasers were generated by the frequency doubling, self‐frequency summing, and self‐frequency doubling processes based on a 1062 nm laser radiation that corresponded to the 4 F 3/2 → 4 I 11/2 transition of Nd 3+ ions. Further, the wavelength tunability for the violet and blue lasers was achieved by simply tuning the pump wavelength within the 4 I 9/2 → 4 F 5/2 transition. The results obtained indicate that Nd:YAB waveguides are promising candidates for efficient compact visible laser sources. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
