Laser induced continuum structure of krypton
G.J. Bottrell, Wallace L. Glab
Ionization, and in particular ionization using lasers, is one of the most important tools we have for examining the structure of atoms and molecules. However, one difficulty is that the bound-free transition probabilities can be rather weak. By taking advantage of resonant structure in the continuum, we can enhance the probability of transition. The idea behind laser induced continuum structure is to create the desired resonant continuum states by using a second laser tuned to an excited state of the atom. A number of interesting effects can be observed due to interference between the direct ionization channel and the channel that involves excitation to the resonant continuum state followed by induced emission to the excited state followed by ionization from this state. We will discuss theoretical calculations of this effect for krypton, as well as its relation to preliminary data involving experiments done at Texas Tech on this system.
