Description
Summary:Calculations are presented in this paper which show the amount of power that can be expected to be deposited in 3He for typical direct nuclear-pumped (DNP) lasers presently in use. The calculations were performed taking into consideration the cylindrical geometry of the system, the depletion of the thermal flux across the tube cross section, and the energy loss of the protons to the cell walls. If a laser efficiency of 1% is assumed, the results indicate a steady-state laser output of 12.5 kW from a volume of 152.6 cm3 or 82 W/cm3 can be achieved.
