In this paper, the effect of atmospheric turbulence on laser beam propagation between tops of the high building and the hill behind our university campus at the distance of 1500m is discussed. The typical range of measurable C(n) values, curvature of the laser beam propagation and the focal spots diameter of the laser beam are given, which are agreement with the theory analysis., Trans. of Laser Technology, (China) v16 n2 p65-72, 1992.

From March 17 to 23, 1989, the International Laser and Applications Symposium was held near Zvenogorsk on the Yenisei River, south of Krasnoyarsk in Novosibirskaya Oblast of the Soviet Union. This was one of the international academic symposia on advanced science and technology held by the Soviet Union for the first time since the glasnost policy of opening to the world., Trans. of Jiguang Jishu (Laser Technology) (China), v13 n4 p1-5, Aug 89.

To produce the high-power density of 10,000 watt class C02 laser beams for research on the interaction between high-power lasers and matter as well as far-field experiments, a high-power laser alignment focusing system was developed based on infrared materials available in China. The system has been operated to improve the properties of high-power lasers. These experiments are open to visiting scholars from elsewhere., Trans. of unidentified Chinese language document, p15-19.
