化学氧碘化激光器（COIL）的基本研究是一种非线性置信融合驱动程序，理论上和实验上都有操作，但首先，线圈的重复脉冲操作与一个磁性增益开关被调查。作为一个结果，比Cw振荡器的峰值功率高出3.7次。Theoretical calculation based on？a2D revealed that the pulse width of the COIL by the switch must be approximately 50？s determined by the energy transfer between O？D22？D2（イイD11？）and I？D22？D2。Second，another repetitively pulsed operation of the COIL was tested。一种多孔型脉冲单氧发生器（SOG）是为这个特别的实验开发的。脉冲输出功率为4.09焦耳，达到1.27千瓦的峰值功率。However，该设备的临时脉冲宽度已按百万计的顺序计算。关于一个带有主振荡器和功率放大器（MOPA）的脉冲线圈系统的方案可以适合于一个单一阶段振荡器方案的短脉冲放大器，最后，一个混合线圈（I.e.）一种照相分离的碘蛋白激光器利用了porous SOG）被提议用于大光圈放大器。数值计算代码已经开发出来，以估计混合线圈的多路径放大过程。它被预测为，它可以产生157千焦的脉冲能量，超过7.6%的效率，超过1米的平均放大器。结果描述了线圈作为一个吸引力的驱动器。混合线圈驱动器应该为下一个R & D阶段的内部信任融合提供一个很好的候选人来演示。

Fundamental studies of chemical oxygen-iodine laser (COIL) as an inertial confinement fusion driver were conducted both theoretically and experimentally.At first, repetitively pulsed operation of the COIL with a magnetic gain switch was investigated. As a result, 3.7 times higher a peak power than the cw oscillation was achieved. Theoretical calculation based on Dyna2D revealed that the pulse width of the COIL by the switch must be approximately 50 μs determined by the energy transfer between OィイD22ィエD2 (ィイD11ィエD1△) and IィイD22ィエD2.Second, another repetitively pulsed operation of the COIL was tested. A porous type pulsed singlet Oxygen Generator (SOG) was developed for this particular experiment. The pulsed out put energy of 4.09 J with a peak power of 1.27 kW was achieved. However, the temporal pulse width of the device was resulted on the order of milliseconds. Such results suggested that a pulsed COIL system with a Master Oscillator and Power Amplifier (MOPA) scheme could be suitable for the short pulse amplification of the inertial confinement fusion driver, instead of a single stage oscillator scheme.Finally, a hybrid-COIL (I.e., a photo-dissociation iodine laser utilizing the porous SOG) was proposed for the large aperture amplifier. Numerical calculation code was developed to estimate the multi-pass amplification process of the hybrid-COIL. It was predicted that it could produce 157 kJ of pulse energy by a 1m-aperture amplifier with the over all efficiency of 7.6%.The results described above confirmed the COIL as an attractive driver. The hybrid-COIL driver should serve as a good candidate to demonstrate the realization of internal confinement fusion in the next R & D phase.
