    • PURPOSE:To prevent the generation of a poisonous gas, to inhibit the lowering of a laser output and to obtain the laser output stable for a prolonged term by coating the surface of a discharge limiting material with an inorganic insulator, which does not change a composition on the mixing of a laser medium gas. CONSTITUTION:When high-frequency high voltage is applied to a pair of dielectric electrodes 11, an intense silent discharge is generated from a discharge limiting material 16, fillers 17 and the surfaces of the electrodes 11 not coated with an inorganic insulator 19, and the surface of the insulator 19 in the vicinity of the electrodes 11 is exposed to the silent discharge. Consequently, the titled gas laser device is constituted so that each surface of the limiting material 16 and the fillers 17 as the generating sources of a poisonous gas is coated with the inorganic insulator 19, which does not generate the poisonous gas even when it is exposed to silent discharge. As a result, no poisonous gas is generated because the limiting material 16 and the fillers 17 are protected from the heat of silent discharge and an electron bombardment, thus preventing the change of a composition on the mixing of a laser medium gas. Accordingly, a laser output does not lower, and the stable laser output is obtained.
    • 目的:为了防止产生有毒气体,通过用无机绝缘体涂覆排放限制材料的表面来抑制激光输出的降低并获得长期稳定的激光输出,其不改变组成 关于激光介质气体的混合。 构成:当对一对电介质电极11施加高频高电压时,从放电限制材料16,填料17和未涂覆有无机绝缘体19的电极11的表面产生强烈的静音放电, 在电极11附近的绝缘体19的表面暴露于静音放电。 因此,标称的气体激光装置构成为使得限制材料16的每个表面和作为有毒气体的发生源的填充物17涂覆无机绝缘体19,即使在暴露时也不产生有毒气体 静音放电。 结果,由于限制材料16和填料17被保护免于静音放电的热量和电子轰击,所以不会产生有毒气体,从而防止组合物在激光介质气体混合时的变化。 因此,激光输出不降低,获得稳定的激光输出。

    • PURPOSE:To simplify considerably the design of a driving power source required for control by constituting a titled device in such a way that the discharge power between main discharge electrodes can be controlled by the making power of an auxiliary AC power source. CONSTITUTION:Ionization is effected around main discharge electrodes 10a, 10b by the effect of an auxiliary electrode 14 and the larger current can be conducted even if the impressed voltage between the main electrodes is low when a voltage is impressed between the main discharge electrodes 10a, 10b and 11 from a DC power source 17 and an AC voltage is impressed on the auxiliary electrode 14. The discharge impedance between the main discharge electrodes decreases if the auxiliary AC power is applied in the above-mentioned way. The DC discharge power can be controlled with the AC power by subjecting the auxiliary AC power to an amplitude modulation. More specifically, the voltage drop between the main discharge electrodes decreases with an increase in the auxiliary AC discharge power, showing a tendency toward an increase in the max. discharge current of the DC discharge. Not only the impulsive or intermittent control of the DC main discharge by on-off control of the AC power but also the analogical variable control of the main discharge power by the analog amplitude modulation of the AC power are possible.
    • 目的:通过构成标题装置,可以通过辅助交流电源的供电来控制主放电电极之间的放电功率,从而大大简化了控制所需驱动电源的设计。 构成:通过辅助电极14的作用在主放电电极10a,10b周围进行电离,即使当在主放电电极10a之间施加电压时,即使主电极之间的外加电压较低,也可以进行较大的电流, 来自直流电源17的10b,11和AC电压施加在辅助电极14上。如果以上述方式施加辅助AC电力,则主放电电极之间的放电阻抗减小。 通过对辅助AC电源进行幅度调制,可以通过AC电力来控制DC放电功率。 更具体地,主放电电极之间的电压降随着辅助AC放电功率的增加而减小,显示出最大值的增加趋势。 放电电流的直流放电。 不仅可以通过交流电源的开关控制对直流主放电的脉冲或间歇控制,还可以通过AC电源的模拟幅度调制对主放电功率进行模拟可变控制。
