| contents | The method of H- photoionization is interesting for laser assisted charge exchange injection. In this paper, the model and computation of photoionization of negative hydrogen ion by using strong lasers is considered. The development of this work is motivated by using pure lasers for photodetachment of electron from negative hydrogen ion when it is not convenient or not possible to use stripping magnet. Herein we develop a method of calculation of high efficiency photoionization using time dependent wave equation with application of powerful lasers. We compare this precise method of calculation with simplified method of calculation through linear model of cross section interaction. Another mechanism of photodetachment through excitation of the Feshbach resonance is also considered. |
