We have investigated spectral distribution and walk-off effect of second-harmonic generation in a 3-mm-long type I BiB(3)O(6) crystal. Linearly turning ability of the BiB(3)O(6) crystal is confirmed for wavelengths around 800 nm. In addition, the walk-off effect of fundamental beams is quantitatively measured by introducing a little vertical polarization component into pumping fundamental pulses. A conversion efficiency of 28% from fundamental to second harmonic is achieved at a 3.2-GW/cm(2) fundamental intensity.
