Abstract

Noncollinear phase-matching configurations are presented in the case of a molecular crystal, 5-nitrouracil. A very wide angular and wavelength noncritical sum-frequency phase-matching configuration is demonstrated to be of high interest for frequency conversion of a near infrared radiation towards the near UV. This configuration, which exists in most crystals, is characterized in the particular case of 5NU. First experiments, in a non optimum configuration, show frequency conversion yields of 12% in energy in converting a low intensity signal (60-240 μJ per pulse at 930 nm) to the blue, by summing with 1.064 μm radiation.
