Abstract :
LiB3O5 has been found to be phase matchable for sum-frequency generation down to 0.2325 μm at 20.0°C by mixing the Nd:YAG laser wavelength at 1.0642 μm with the second harmonic of a visible dye laser. Sellmeier´s equations, which are highly accurate from 0.22 to 1.32 μm, are reported. It is demonstrated that a much shorter wavelength of 0.218 μm could be generated in this compound by mixing the fourth harmonic of a Nd:YAG laser with the idler of the KNbO3 parametric oscillator tuned to 1.208 μm
