Abstract EN
The plasma holmium produced by a 1064 nm Nd:YAG Q-switched laser in air was investigated.
This work was done theoretically and experimentally.
Cowan code was used to get the emission spectra for different transition of the holmium target.
In the experimental work, the plasma evolution has been studied by acquiring spectral images with different laser pulse energies (600, 650,700, 750, and 800) mJ, with The repetition rates of (1 Hz and 10 Hz).
In the UV region (200-400) nm.
The results indicate that, the emission line intensities increase with increasing of the laser pulse energy and repetition rate.
The strongest emission spectra appeared when the laser pulse energy is 800 mJ and 10 Hz repetition rate at λ= 345.64 nm, with the maximum intensity of 77000 counts
