到目前为止,CO_2激光器的研究经历了二十年的努力,近年来已经进展到一个新的阶段,就是探讨在军事领域里应用更为经济和更为有效的问题。经一些研究资料表明,作为战略上用的CO_2激光器在微波雷达发展已有相当基础,激光雷达的历史还比较短时,应向红外CO_2激光雷达组合化方向发展。因此,重点应放在如何提高CO_2激光器的质量、可靠性、输出功率及小型化方面。本文分析了研究向红外激光雷达过渡的必然性。 So far, the CO 2 laser has undergone two decades of hard work and has moved into a new phase in recent years in which it explores the application of more economical and effective problems in the military field. After some research data show that as a strategic CO_2 laser microwave radar has been in the development of a considerable basis, the history of the laser radar is still relatively short, should be combined to the direction of development of infrared CO_2 laser radar. Therefore, the emphasis should be placed on how to improve the quality, reliability, output power and miniaturization of CO2 lasers. This article analyzes the necessity of studying the transition to infrared laser radar.
