抄録

Topical experimental results of artificial star generation are presented. The generation system utilizes a 1.5 m diameter telescope of CRL for transmitting a laser beam to illuminate the atmosphere and for receiving backscattered light. The light source of transmission used is the second harmonics of a pulse-oscillating Nd: YAG laser. A mirror with a small hole at its center is used as a beam splitter for transmission and reception, and it spares us from a power loss of about 6 dB compared to the use of a conventional beam splitter. We executed the first domestic experiment of artificial star generation by atmospheric Rayleigh-scattering, and succeeded in acquiring image data of artificial stars generated at ranges up to ten plus several kilometers. At the same time, data of Polaris in a neighboring direction were obtained as a reference and image comparison.
