It is suggested that three-wave parametric fluorescence in optically anisotropic crystals, e.g. KDP, may be used to generate high intensity (>=1GW/cm3), broad-bandwidth (delta lambda/lambda<=5-10%) light with small divergence (<=100 µrad) in the near infrared to midvisible spectral regions. Larger fractional bandwidths and shorter wavelengths may be achieved by modification of crystal optical properties and harmonic conversion or sum frequency generation, respectively.
