Analytical Time Resolved Laser Enhanced Ionization Spectroscopy. I. Collisional Ionization and Photoionization of the Hg Rydberg States in a Low Pressure Gas
The temporal behaviour of the laser enhanced ionization signal of mercury was studied in a quartz cellunder low buffer gas pressure. Using fast electronics and a short (34 ns) laser pulse, it was possible to distinguish, in one single time-resolved ionization waveform, the non-selective photoionization component of the signal from that which was due to collisional ionization from selected levels. Experimental results were shown to agree with those obtained by computer simulation, and optimal conditions for deconvolution of the two components were studies.
