Laser Cooling of Recombining Electron-Ion Plasma

A method of producing and confining ultracold electron-ion plasma with a strongly nonideal ion subsystem is considered. The method is based on the laser cooling of plasma ions by the radiation resonant with the ion quantum transition. A model is developed for the laser cooling of recombining plasma. Computer simulation based on this model showed that the ion nonideality parameter can be as large as ∼100. The data obtained demonstrate that the production of ultracold nonideal plasma is quite possible.
