We have studied under laser diode pumping near 800 nm the continuous wave laser operation of the Nd(3+) -doped La(2)CaB(10)O(19) biaxial noncentrosymmetric crystal. From Z-oriented samples we have obtained lasing at 1051.4 nm of Nd(3+) ions located in the regular La(3+) sites. Self-frequency doubling was obtained with samples oriented at the phase matching direction of the type I ee-o nonlinear interaction. With X-oriented samples, thanks to the existence of two La(3+) and Ca(2+)-sites for the Nd(3+) location, we have obtained a two-frequency laser working in dual polarization with a frequency difference unusually large of 4.6 THz.
