Copper emission lines for temperature measurements of the plasma produced by nano-second laser

الملخص EN

The aim of the present work is to measure the plasma temperature of the plasma generated by focusing an intense laser beam on copper target in air at atmospheric pressure.

The plasma is generated using two different laser wavelength (1064 and 532 nm) and for different laser energies.

Plasma is generated using a Brilliant Nd YAG pulsed laser from Quantel laser and the emission spectrum is collected using an Echelle spectrometer equipped with ICCD camera Andor type.

The temperature is measured by developing a Boltzmann plot from three Cu I spectral lines at 510.55, 515.32, 521.82 nm.
