چکیده
|
In this paper, the dynamic behavior of laser induced optical breakdown in impure water was studied by using a pump- probe technique. the plasma was induced by a 1064 nm nd:yag laser pulse (with pulse duration ~10 ns) in distilled water with two types of impurities: (i) a solution (highly diluted salt water as a conductor) and (ii) a colloidal (tio2 in colloidal nanoparticle form as a dielectric); and finally the results were compared. the results show that, for both liquids, the probe beam transmission is reduced with pump laser intensity. our results also show that, impurity size and type of conductivity can influence on plasma time evolution and transmissivity.
