| Abstract | ||
| The electrical properties of Cr+4:YAG crystal had been calculated as [ dielectric constant (ε) , dielectric time (τdie) , permittivity (Є) , permeability (μ) , electrical response time (TE) , laser wave propagation speed through crystal (VP) , skin depth (δ) , electrical susceptibility (χ ) , crystal impedance (Z ) , electrical conductivity (σ ) , induced electrical polarization (Pin) , molar polarization (ρp) and wave number (K) ] and some of other properties as ( transmittance (T) and refractive index(n)) at (90% and 95% ) initial transmission for saturable absorber (Tu) , in the passively Q-switched mode –locked (QML) Nd:GdVO4 laser system at (912nm). It can be concluded that each of electrical and magnetic flux density in Cr+4:YAG crystal which was incurrence to laser wave are mainly dependent on free electrons exists in it , while the electrical polarization are dependent on the number of crystal molecules in the ground-state . | ||
