Phase-Matching Effect in High-0rder Harmonic Generation
The phase matching effect on high order harmonic generation was studied by using a 45 fs 2 TW Ti:sapphire laser pulses, especially the effect of gas density, laser intensity and confocal parameter. It is found that there are an optimal gas density and an optimal laser intensity with regards to the improvement of phase matching. The weak focusing geometry is more favorable for higher conversion efficiency than the tight one.
