Abstract
The results of experimental study of a gas-discharge Ne-Eu laser are presented. In this work, lasing lines, pulse shapes in europium atom and ion in the conditions of this experiment are identified. Influence of the buffer gas pressure and pulse repetition rate on the energy characteristics of the laser is ascertained; their optimal values are determined. It is shown that under optimum operating conditions for the corresponding transitions the output power is 1 W at 1759 nm line and 70 mW at 664.5 nm line.
