研制了适用于激光器的电感储能发生器（GIES）,并研究了它在高压混合气体中的放电和激光参数。研究表明,电感储能发生器可产生高压预脉冲并引起放电电流的突然增大,可在不同的混合气体中形成长时间的稳定放电,从而方便地控制和优化每一种气体混合物的预脉冲参数。在未知IES击穿电压和首次放电幅度下的参数时,电流尖峰会按因子1.52减少,从而产生纯激光参数。得到了氮气激光器的最大的辐射功率,输出能量和脉冲持续时间,在脉冲持续时间为40 ns时,紫外输出高达50 mJ,红外输出高于25 mJ,实现了氮分子激光跃迁的级联激射。因此C^3Пu-B^3Пg带总的脉冲持续时间延长至100 ns。在XeCl,Xef和Krf受激准分子激光器中,脉冲宽度和输出能量都得到了改善。Xef激光器的最大效率达到了1.6%,同时峰值输出能量达到了0.85 J,最大脉冲持续时间超过了200 ns。在248 nm波长处,效率3.3%的Krf激光器产生的160 ns脉冲能量高达650 mJ,最终得到了效率为7.7%10%的非链式Hf（Df）激光器。演示了基于CO2分子高峰值功率的有效运行,结果表明,激光器在10 600 nm处的输出能量为6.2 J,转换效率高达25%。

In the work, we studied the effect of the plasma of a runaway electron preionized （REP） diffuse discharge （DD） on the composition, structure, and properties of ST3PS steel surface layers. Voltage pulses with an incident wave amplitude of up to 30 kV, fWHM of around 4 ns, and rise time of around 2.5 ns were applied to the gap in an inhomogeneous electric field. The ST3PS steel specimens exposed to this type of discharge revealed changes in their defect subsystem, suggesting that the runaway electron preionized diffuse discharge provides surface hardening of the steel.

The formation of runaway electron pre-ionized diffuse discharges at the pressures 0.05-0.7 MPa of in air, argon, nitrogen, and Sf6 in an inhomogeneous electric field was investigated. Dynamics of intensity of the discharge plasma radiation from the different discharge gap regions in the gas pressure range （0.05-0.7 MPa） was established. It was shown that, the breakdown is occurred owing to the ionization wave, which starts from the electrode with small radius of curvature at both polarity of high voltage pulses. It is seen that formation of bright spots on the fiat electrode at the negative polarity of the electrode with small radius of curvature are observed during the changing of the discharge current polarity. It was shown that, at positive polarity of electrode with a small radius of curvature, the bright spots on the flat electrode arise due to the participation of the dynamic displacement current in the gap conductance.
