摘要
从激光器类型、激光脉冲能量、激光脉冲宽度、导光及聚焦等方面对激光声遥感技术中应用的激光器提出了具体的技术要求,并重点介绍了如何通过在激光器中采用特殊结构的非稳腔、精确的放电腔、Fitch脉冲电压发生器、望远镜聚焦系统等设计思想来实现以上技术要求。应用效果表明,根据以上设计思想研制出的二氧化碳激光器能够满足激光声遥感应用要求。
The technical requirements about the laser employed in laser-acoustic remote sensing are put forward,and design principle of the laser is presented.The technical parameters is related to laser type,laser pulse energy,laser pulse duration,leading and focusing of light etc.The design ideas are related to special unstable resonator,precise discharge chamber,Fitch pulsed voltage generator,telescopic focus system etc.The application shows that the pulsed CO2 laser developed according to the above-mentioned design ideas can meet the demands of laser-acoustic remote sensing technique practically.
