Sum-frequency mixing in neodymium-doped YAl3(BO3)(4) of its fundamental las
er Line at 1062 nm and the pump light from a tunable Ti:sapphire laser has
been used to generate blue radiation from 435 to 465 nm in an end-pumped co
nfiguration. In nonoptimal preliminary experiments 22 mu W at 458 nm was ob
tained out of 200 mW absorbed power at 807 nm. Nd:YAB, therefore, emerges a
s a promising laser material for diode-pumped solid-state lasers in the blu
e spectral region. (C) 1998 American Institute of Physics. [S0003-6951(98)0
