摘　　要：对用Blumlein电路放电激励的钡蒸气激光在掺氢和不掺氢时的输出特性进行了实验研究 .结果表明 ,用掺氢1 5 %的氖气作缓冲气体能使激光功率增加近 2倍 .在此基础上 ,进一步比较了相互作用电路与Blumlein电路时钡蒸气激光的输出特性 ,发现相互作用电路能显著提高钡蒸气激光的输出功率和效率 ,获得了 3W最大功率和 0 4 %效率的 1 5 μm波长激光输出 .测量并分析了各工作参量与激光功率之间的关系 。The output performances of barium vapor laser with and without hydrogen additive excited by pulsed discharge with Blumlein circuit were experimentally investigated. The result indicates that the laser output power increases two times with 1.5% hydrogen mixed into the neon buffer gas. Based on this experimental result, this paper further compares the working characteristics of barium vapor laser with interactive circuit and Blumlein circuit, and finds that the interactive circuit can greatly improve the laser output power and its efficiency. The maximum laser power of 3 W and efficiency of 0.4% have been obtained at 1.5μm laser line. The dependence of laser power on working parameters is measured and discussed, and the mechanisms of hydrogen additive and interactive circuit for improvement of the laser performance are qualitatively analyzed.
