We report here the growth and characterization of non linear single crystals β BaB2O4 (BBO) which is an interesting material for second harmonic generation. Single crystals were grown from Na2O-B2O3 solutions using the top seeded solution growth method. The experimental set up included a Nd:YAG, Q switched, focalised with a cylindrical lens on the samples. Efficiency up to 40 % were obtained using 6 mm long crystal.
