摘要：
Harmonic generation in barium metaborate (BBO) by femtosecond Ti:sapphire laser pulses is studied, taking into account both the group velocity mismatch and the lowest and second order group velocity dispersion (GVD). The lowest and second order GVD is calculated as a function of wavelength in the BBO crystal. Second and third harmonic radiation using femtosecond Ti:sapphire laser pulses is computed numerically by solving the coupled wave equations. The effects of the lowest and second order GVD on the fundamental and the harmonic pulses are analyzed. The compensation of group velocity mismatch in sum frequency processes for third harmonic generation is considered.
