For the efficient second-harmonic generation of ultrashort pulses in wide spectral ranges, we theoretically studied all possible group velocity matched broadband frequency conversion processes in different periodically poled materials, using quasi-phase matching. Important parameters such as the poling period, type of interaction, spectral bandwidth and conversion efficiency are estimated in detail. The results show that some materials can be efficiently applied to the generation of sub-100 fs pulses near the wavelengths of a widely used Ti:sapphire laser.
