ABSTRACT
Laser induced thin film production (LITFP) technique was employed for making plumbum (Pb) thin film by nitrogen laser deposition in miniature scale. The energy of nitrogen laser operated at 12.5 kv, 90 torr was 3.5 mj with 5 ns pulse duration, thus producing peak power at around 0.7 MW. Pb plasma of 1 cm diameter was generated in each laser bombardment, producing thin film above the glass substrate.
The thin film characteristics were ...

ABSTRACT
In spite of abundant experimental evidences supporting the viability of the laser
induced shock wave plasma model for the explanation of the important features ofthe
plasma and the associated spectroscopic characteristics, a controversy on the atomic
excitation mechanism in the plasma has remained to be completely resolved. In this
study the contributions of the shock wave model and two other most popular models,
the electron-ion recombination model and thc electron collision model were
thoroughly investigated. For that purpose, a special technique ...
