Abstract
When the Ne + Tl gas-vapor mixture was excited by an electron beam, laser generation was obtained and investigated with excitation of the upper levels in the charge exchange reaction at ion lines with λ = 1,922; 1,385; 0,595; 0,695 and 0,707 mm; the lasing at the first two lines was obtained for the first time. In the studied range of pump parameters, a linear dependence of the lasing power on the pumping power was revealed, indicating the efficiency of electron-beam excitation. An average radiation power of 44 mW was reached at λ = 595 nm at a pulse repetition frequency of 1 kHz with an efficiency of ~ 0,06%. A numerical simulation of the laser energy characteristics was carried out.
