INFLUENCE OF LASER SATELLITE TRANSITIONS ON SPECTROSCOPY OF HIGH-INTENSITY LASER-PRODUCED PLASMAS

摘要

The oscillating electromagnetic field of an intense laser pulse can significantly affect the emission properties of ions in a plasma. For sufficiently intense laser fields, induced second order processes produce discrete radiative transitions. In addition, these induced radiative processes alter the level population kinetics, and the spectrum of spontaneous transitions. We discuss the effects of these processes on the n = 2 - 1 spectrum of He-like ions, as well as implications for some x-ray laser schemes pumped by intense, short-pulse lasers.
