| Abstract: | Parametric properties in femtosecond optical parametric conversion process based on the new nonlinear crystal BiB3O6 (BIBO) are studied. The phase- matching conditions and effective nonlinear coefficients in the three principal optical planes of the BIBO crystal are calculated, optimum principal optical planes and phase -matching types are determined when using the fundamental frequency and the frequency doubling of the KLM Ti:sapphire laser as pump respectively, and temporal walk-off and spatial walk-off of three waves, and signal parametric gain and bandwidth are analyzed. We thereby provided a theoretical basis and experimental guide for obtaining the light source with high energy, wide tuning range, and short duration with femtosecond optical parametric technology based on the BIBO. |
