| 摘 要： | 高功率大型惯性约束聚变(ICF)激光驱动器大多采用等离子体电极普克尔盒(PEPC)抑制多程放大器的自激振荡和隔离反激光。采用并联驱动技术有利于实现等离子体电极普克尔盒电光开关小型化和降低成本，并可提高激光系统可靠性和稳定性。等离子体电极普克尔盒的并联驱动包括等离子体电极的并联驱动和普克尔盒充电的并联驱动。分析了等离子体电极电光开关并联驱动的途径和问题，通过采用电阻隔离和二极管退耦措施实现了预电离并联驱动，进而实现了等离子体电极的同步驱动；通过调节开关脉冲发生器输出波形及传输电缆长度，可实现普克尔盒充电的并联驱动，并给出了实验结果。 |

| Abstract: | Plasma electrode Pockels cells (PEPC) are used in large high power laser driver for inertial confinement fusion (ICF) to restrain the self oscillation produced by the multipass amplifier and isolate the back beams. With parallel driving technology, the miniaturization and low cost of Pockels cells driver can be realized. In this paper, the approaches and issues of parallel drive for PEPC electro optical switches are described. The parallel drive electro optical switches include the parallel driving of plasma discharge and switching crystal charge. With the isolate resistance and decouple diode, the pre ionization of two Pockels cells are parallel driven successfully. Moreover the plasma electrodes of two Pockels cells are accuracy synchronously taken place. By adjusting the forming line of switch pulses and transmission cable length, the parallel charge of Pockels cells can also be achieved. And the experimental results are given in the end. |
