A simulation code for tempo-spatial analysis of three-wave interaction with ultrashort- and ultrahigh-intensity laser pulses

We have developed a simulation code that can be used for tempo-spatial anal ysis of three-wave interaction with ultrashort- and ultrahigh- intensity la ser pulses. The code can be used to estimate conversion efficiency, tempo-s patial and spectral profiles and many transverse effects including diffract ion, walk-off, phase modulations and self-focusing through the third-order nonlinear process. An application example of the code to second-harmonic ge neration is given in this short note.
