激光陀螺引燃技术研究及应用

Research and application of laser gyro ignition technology

针对棱镜式激光陀螺引燃不可靠的现象,系统地研究了基于外置电极加载高频电场激励激光器件谐振腔的引燃方法,理论上分析了影响激光陀螺引燃电压的获取因素,在此基础上提出了两种增加谐振腔引燃可靠性的措施,通过缩短引燃阴极和引燃阳极之间的距离,有效降低了谐振腔所需的引燃电压值,从而使工作气体局部更容易被激发,进而产生雪崩效应,使整个内部空间的工作气体被激发,实现激光器件谐振腔的正常持续工作。实验结果表明,优化后的激光陀螺谐振腔在高、低、常各温度段可实现大于99.9%的可靠引燃。

Aiming at the phenomenon of unreliability of prism laser gyro ignition,the ignition method of laser device resonator excitation based on external electrode loading high frequency electric field is systematically studied.The factors influencing the acquisition of laser gyro ignition voltage are theoretically analyzed.Based on this,two measures are proposed to increase the ignition reliability of the resonant cavity.By shortening the distance between the ignition cathode and the ignition anode,the required ignition voltage value of the resonant cavity is effectively reduced,making it easier for the working gas to be locally excited,and then produce an avalanche effect,so that the entire internal space of the working gas is excited,to achieve the normal continuous operation of the laser device resonator.the experimental results show that the optimized laser gyro resonator can achieve more than 99.9%reliable ignition at high,low and constant temperatures.
