Comparative Study Of Resonator Optics For Lidar Applications

Report discusses overall transmit/receive performances of laser-radar transceivers. Gaussian case and hard-edged case selected for comparison because of their practical importance. Intercomparison shows that for multi-joule-output pulsed CO2 lasers, Gaussian profiled optics offers little improvement over hard-edged option, while greater hardiness and superior energy extraction capability of latter constitutes strong argument in favor of its application.
