Simultaneous generation of violet, blue, and green lasers using Nd:YAl3(BO3)4 channel waveguides under pumping at 815 nm

Violet, blue, and green lasers were simultaneously generated by nonlinear processes using ultrafast laser inscribed neodymium-doped yttrium aluminum borate (Nd:YAl3(BO3)4 or Nd:YAB) channel waveguides under pumping at 815 nm. These visible lasers were generated by the frequency doubling, self-freque...

Descrição
Resumo:Violet, blue, and green lasers were simultaneously generated by nonlinear processes using ultrafast laser inscribed neodymium-doped yttrium aluminum borate (Nd:YAl3(BO3)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 4F3/2 → 4I11/2 transition of Nd3+ ions. Further, the wavelength tunability for the violet and blue lasers was achieved by simply tuning the pump wavelength within the 4I9/2 → 4F5/2 transition. The results obtained indicate that Nd:YAB waveguides are promising candidates for efficient compact visible laser sources
