CW laser pumping of the 4s21S0-4s4p3P1transition of calcium: study of ionization and absorption line profiles
Muhammad Arshad Khan, Mohammad F. Al-Kuhaili
Experimental results on the ionization of calcium atoms following resonant pumping of the 4s 2 1 S 0 -4s4p 3 P 1 transition with a CW ring dye laser are reported. Absorption profiles of the 4s 2 1 S 0 -4s4p 3 P 1 transition around 6572.78 AA are measured under different conditions of temperature (T) and buffer gas pressure (p) where ionization was observed. Voigt profile fits are seen to adequately describe the observed absorption profiles. The results on collisional widths are in agreement with some previously published measurements. At low buffer gas pressures, collisional widths are found to scale as T 0.5 .
