G. Foulon et al., NONLINEAR SINGLE-CRYSTAL FIBERS OF ND3-DOPED NIOBATES (BA2NANB5O15 AND K3LI2-XNB5+XO15+2X) GROWN BY LHPG, SPECTROSCOPY AND SELF-FREQUENCY DOUBLING(), Journal of luminescence, 72-4, 1997, pp. 794-796
The obtention of good quality and crackless Ba2NaNb5O15 (BNN) and K3Li
2-xNb5+xO15+2x (KLN) single-crystal fibers doped with different amount
s of Nd2O3 is reported. Structural data for each crystal, low-temperat
ure spectroscopy and second harmonic generation (SHG) studies show tha
t these single-crystal fibers are potentially self-frequency doubling
and sum frequency self-generating laser materials.
