In LiIO3 and BBO crystals the wave-matching conditions for femtosecond noncollinear parametric light generation at λ = 390 nm pumping wavelength are investigated. In the LiIO3 crystal simultaneous phase- and group-velocity-matching angles are determined. Parametric generation occurred at 0.45–2.9-μm wavelengths by pumping with the second harmonic of 150-fs Ti:sapphire laser pulses and is in qualitative agreement with calculated directions in both crystals.
