Relationship between molecular dipole moments and frequency doubling effects in some organic crystals
Li Songxian, Li Junqian, Chen Jianzhong, and Wu Bochang
The article has proved preliminarily connection of dipole moments and frequency doubling effects of organic conjugate molecules. The molecular dipole moments of 3-methyl and 2-tmethyl-4-nitropyridine-l-oxide (3-POM and 2-POM) and 2-halogea and 3-halogen-4-nitroniline (2-CNA, 3-CNA, 2-BNA and 3r-BNA) have been calculate

Infrared absorption of water in phosphate laser glasses
Mao Sen, and Mao Hanfen
Infrared absorption spectrum of phosphate glasses was measured and absorption peaks at 3.5pm, 4.25pm, 6.0pm were obtained. Further studies on the influence of A1S03 content and alkali oxide content in phosphate laser glasses on the absorption band have been mode. It is shown that the density and strength of phosphate l

Further studies on the influence of A1S03 content and alkali oxide content in phosphate laser glasses on the absorption band have been mode. It is shown that the density and strength of phosphate laser decrease with the increasing water content..

Recrystallization of polysilicon films by Ar
+
laser irradiation
Lin Chenglu, Shen Zongyong, Fang Fang, Lin Zixin, and Zon Shichang
CW Ar+ laser is used for recrystallization of polysilicon films on isolating layers. Experimental results show a large increase in grain size, significant improvement in electrical properties and compatibility with conventional integrated circuit technology.

Analysis of errors in regulation of cylindrical step-index optical waveguide fiber with a spherical lens excited with GaAs lasers
Zhang Zhipeng, and Shi Shouyong
This paper analyses how the exciting efficiency is influenced by errors in the regulation of cylindrical step-index optical waveguide fiber with a spherical lens excited with GaAs lasers. It shows that the influence of transversal offset is much more than that of axial regulation error, and the former causes the exciti
This paper analyses how the exciting efficiency is influenced by errors in the regulation of cylindrical step-index optical waveguide fiber with a spherical lens excited with GaAs lasers. It shows that the influence of transversal offset is much more than that of axial regulation error, and the former causes the exciting efficiency of fundamental modes to decrease little faster than an exponential function does..

Measurement of skin diffuse reflectance ratio of laser radiation
Gao Guanghuang, Zhang Guisu, Chen Zongli, Li Weining, and Wang Denglong
The laser diffuse reflectance at 694. 3nm on the pig and human skin was measured by a self-made reflectometer. The data were given for the experiment of laser damage threshold. The diffuse reflectances ratio at 530 nm, 632.8 mn, 694.3 and 1060nm at different places of human skin were obtained.

The paper reports the preliminary results of ultraviolet erythema on the skin irradiated with 308 nm excimer lasor light. Using white porkel as an animal model, we obtained the data on the injury thresholod of the skin. 95% fiducial limit of MBD50, in which energy will result in 50% perceptible redness occurence rate in all points irradiated at this exposure dose, ranges from 45.97 to 63.05 mJ/cm2..

Injury threshold of cornea by CO
2
laser light exposure
Xu Jiemin, Zhou Shuying, Hu Fugen, Cao Weiqun, Xu Guidao, Qian Huanwen, Wang Denglong, and Shi Liangshun
The minimal visible lesion in the corneal epithelium resulted from exposure to C02 laser light has been carefully determined. The dose to cause 50% damage probability (ED50) varied with time of exposure: for 1.03 s was 5.72 W/cm2 (95% GL 5.8~5.85 W/cm2) and for 0.12 s was 10.7 W/cm2 (95% CL 10.4~10.9 W/cm2).
