Abstract

Lasing at Tl⁺ lines with λ = 1.922, 1.385, 0.595, 0.695, and 0.707 μm was obtained when pumping a Ne + Tl gas-vapor mixture by an electron beam and creating population inversion of Tl⁺ transitions in the charge exchange reaction; the lasing at the first two lines was implemented for the first time. A linear dependence of the lasing power on the pumping power was derived in the range of pumping parameters under study, which proves the efficiency of the electron-beam excitation. An average lasing power of 44 mW was attained at λ = 595 nm at a pulse repetition frequency of 1 kHz with an efficiency of ∼0.06%. Energy parameters of the laser were numerically simulated.

电子束激发T离子激光器的激光发射特性

摘要

当通过电子束泵浦Ne + Tl气体-蒸汽混合物并在电荷交换反应中产生Tl ⁺跃迁的种群反转时，获得了λ= 1.922、1.385、0.595、0.695和0.707μm的Tl ⁺线的激光发射；前两行的激射是第一次实施。在研究的泵浦参数范围内，得出了激光功率与泵浦功率的线性关系，证明了电子束激发的效率。在1 kHz的脉冲重复频率下，λ= 595 nm处的平均激光功率为44 mW，效率约为0.06％。数值模拟了激光的能量参数。
