Abstract :
We have studied the dependence of the THG bandwidth on various laser and material parameters. It is found that the bandwidth of a THG signal is strongly dependent on the relative distance of laser focal plane to the material interfaces and laser numerical apertures. The results are important to obtain a high-yield and broad bandwidth THG signal for applications such as characterizations of ultrashort optical pulses.
