Abstract

The kinetic behaviors of 6p[1/2]₀, 6p[3/2]₂ ,and 6p[5/2]₂ were examined under the ultrahigh pumped power. These processes were detected by the way of time-resolved fluorescence and ASE spectra. A theory of energy-pooling is presented under the focused condition. There are three types of energy-pooling processes. The first type is energy-pooling ionization. The obvious ionization can be observed whenever the laser prepared state is the 6p[1/2]₀, 6p[3/2]₂, or 6p[5/2]₂ state. The second type is energy-pooling with big energy difference. The energy-pooling collision between the two 6p[1/2]₀ atoms can produce one 5d[3/2]₁ atom and one 6s’[1/2]₀ atom when the prepared state is 6p[1/2]₀. The third type is energy-pooling with small energy difference. The way of generation of five secondary 6p states is energy-pooling instead of collision relaxation.
