ENEA遥感实验室开发了一种紧凑型二氧化碳激光光源，目的是沿同一条线路快速连续发射两种交替波长，用于激光雷达/Dial应用。新设计中采用的解决方案成功地克服了以前在运行激光雷达试验场时遇到的许多问题。两个不同波长的光束从一个腔中重叠发射，是对传统系统的重大改进，传统系统依赖于两个独立的激光光源在不同的线路上工作。接收器和捕获电子设备的额外升级导致了整个激光雷达系统性能的进一步改进。新的设计系统代表着朝着发展紧凑型全机动激光雷达迈出的重要一步。
A compact carbon-dioxide laser source has been developed at the ENEA remote sensing laboratory, with the aim of emitting two alternate wavelengths in rapid succession along the same line for use in lidar/DIAL applications. The solutions adopted in the new design successfully overcome many of the problems previously encountered running a lidar test site. The overlapped emission of two different wavelengths beams from a single cavity is a major improvement on the traditional systems which relied on two separate laser sources operating on different lines. Additional upgrading of the receiver apparatus and of the acquisition electronics have led to further improvements in the performance of the complete lidar system. The new design system represents a significant step towards the development of a compact fully mobile lidar.
