Abstract
Short THz pulses can be generated by focusing an ultrashort laser pulse and its second harmonic simultaneously in ambient air and generating plasma. The process is efficient in the right circumstances, but sensitive to the relative phase between the two pulses and the initial group delay dispersion (GDD) of the fundamental beam. Previously it was found that zero initial dispersion and π/2 relative phase is the optimal for most cases. In this work, the connection between the nonlinear crystal thickness and the spectral phase properties has been also studied for THz generation. It has been found there are conditions where the THz spectral bandwidth can by continuously tune in the function of the GDD value. It has been also found that the optimal crystal thickness strongly varies with the laser energy, hence with the peak intensity.
