Spectral characteristics of gas discharge ion lasers on vapors of thallium and gallium
- 20 Downloads
The results of calculation and measurements of the hyperfine and isotopic structure splitting of laser lines of thallium ion (λ594.9 nm and λ695 nm TlII) and gallium ion (λ633.4 nm GaII) are presented. That is caused by hyperfine splitting of upper and lower laser levels on some sublevels, and also by the shift of sublevels energy taking place because of volume isotopic effect for different isotopes which are present in the natural mixture of each metal.
