Development of transverse-flowing CW CO2 laser without helium
Gong Zhiwei, Xue Jing, Tang Zhonghna, Yung Yu, Qiu Junlin
1989, 13(1): 1-5.
Abstract:
1kW laser output has been realized by replacing helium (CO2-N2-He) with argon(CO2-N2-Ar) and stable operation is obtained at the level of 1.2 kW laser output by using CO2-N2 in the transverse-flowing CO2 laser.
The production of pulse light pressure and its applications
Zhu Lianxin, Yu Changhe
1989, 13(1): 6-13.
Abstract:
We found the pressure phenomenon of pulse light in a laser cavity in August 1975.In order to explore its applicable significance, we have made some experiments and got more satisfactory results on the principle and applications.

Laser receiving and aiming system
Yu Jinxiag
1989, 13(1): 14-20.
Abstract:
The optical system introduced here is an optical antenna designed for ship-loaded gun-controlling laser ranger. This antenna has come into use in our institute. It has receiving and aiming two functions. The principle of operation, determination of parameter,receiving and aiming double waveband spectrum type and handling of aberration are introduced in this article. The design results is also given out here.

Investigation of CO2 laser parametric unconversion
Zhong Ming, Han Kai
1989, 13(1): 27-30.
Abstract:
The opresent paper first reports investigation results of CO2 laser upconversion in an AgGaS2 crystal into near infrared radiation detected by an avalanche photodiode SPD-052. A value of the noiseequivalent power (NEP)~3.8×10-8W, or the normalized detectivity (Dλ#)~1010cmHz1/2W-1 has been obtained. The power conversion efficiency of type Ⅱ noncollincar phase matching is estimated to be 10%.

Gui Zhenxing, Zhang Shunyi, Shen Guirong
1989, 13(1): 39-41.
Abstract:
The experimental results show that provided that discharge region is sufliciently cooled in a cavity of CO laser higher output power can be obtained.
Measurement of micro wedge angles of glass plates
Xiao Minghai, Wang Guohua
1989, 13(1): 42-45.
Abstract:
A new experimental method for checking micro wedge angles of glass plates is presented. The method uses laser speckle technique to record the shift amount of speckle patterns due to micro wedge angles, and thus micro wedge cangles of the test piece are induced. The method is characterized by simple light, mon-contact and high accuracy.
