Numerical analysis of molecules intersystem crossing effect on a passively Q- switched laser pulse characteristics

Abstract

The effect of molecules intersystem crossing (Kisc) on characteristics (energy and duration) of a Passive Q- switched Laser Pulse has been studied by mathematical description (rate equations model) for temporal performance of which was used as a saturable absorber material (passive switch) with laser. The study shows that the energy and duration pulse are decreasing while the molecules intersystem crossing into saturable absorber energy levels is increasing.
