摘　　要：燃烧驱动全气相碘激光器需要通过燃烧产生所需要的氟原子,但是用于点火的脉冲源对微弱信号测试产生了严重干扰。为了解决燃烧驱动点火控制脉冲源对微弱信号测试的干扰,基于燃烧室内气体一旦点燃压力就迅速升高的特点,采用仪表、集成电路等研制了一套具有反馈控制的闭环点火控制系统。对系统的工作原理和硬件组成分别进行了介绍。实验表明,本系统既可以保证系统正常点火,又能保证系统在无干扰的情况下实现测试。Combustion-driven all gap phase iodine laser needs fluorine atoms which are produced by the combustion process. But the control pulse, which is used to drive ignition, has serious disturbance to the weak signal detection. Because once the mixture of gas is ignited, the gas pressure in the combustion chamber will increase instantly. So gauges and integrated circuit etc are used to develop a set of ignition controlling system that has the function of feedback-control close-loop ignition. In this paper, the mechanism of system control and the components of system are introduced in details. Finally experimental re sults indicate that the control system ensure the combustion system ignite normally, and fulfill the non-disturbance signal de- tection condition as well.
