The solidified tendency of tuned laser
Zhang Guowei
1992, 16(6): 321-326.
Abstract:
Based on the development of the solid tuned lasers,such as Ti doped sapphire etc,in this area of tuned laser,there recently appears the developmental tendency to transfer from liquid (dye) laser to solid (transit ion or optical parameter oscillation)tuned laaer. This paper appraises the tendency and the developmental direction of all-solidified tuned laser.

Study on the intrinsic structure defects in core location of YAP crystal stick by means of 60Co irradiading and PAT
Shi Zikang, Wu Jinhua
1992, 16(6): 342-349.
Abstract:
In this paper,the intrinsic structure defects of 1% Nd: YAP crystal core have been researched by using 60Co irradiation and spectrum measurement of positive electron life,named "immersion". The research results show that the "immersion" technique is a good method to improve structure defects of Nd:YAP crystal core.Annealing in 1100 hydrogen atmosphere for 10h has fade function,but additional action is permitted not to neglect.

Development of a beam splitter coated with step-reflectivity film
Luo Zhenkun, Xu Shuxiang, Xie Zhongming, Li Weining, Ma Ping
1992, 16(6): 354-356.
Abstract:
This paper introduces a practical dielectric film beam splitter.The splitter has the properties of less energy absorption,higher optic damage threshold,good optical homogeneity and beam splitting with step ratio.It can be used in visible laser and Q-switch laser. The experimental results are given and discussed.
The measurement of absorption and small signal gain coefficient of the first triplet transition of the sodium dimer
Wang Qi, Liu Wei, Liu Jincheng, Ma Zuguang
1992, 16(6): 357-361.
Abstract:
This paper reports the measurement of absorption and small signal gain coefficients of the first triplet transition of the sodium dimer.The small signal gain coefficient is larger than the absorption coefficient in the whole spectral region,which also confirms the possibility of the laser oscillation in this region.

Study of a tuned and monolithic He-Ne laser
Ma Younian, Ding Jinxing
1992, 16(6): 362-365.
Abstract:
This paper introduces a simple and monolithic He-Ne laser with a tuned construction.The experimental results show that the laser can work at several wavelengths with the tuned construction,such as 543 nm(green),594 nm(yellow),605 nm,612 nm(orange),633nm and 640 nm(red).The output characteristics are discussed.
Temporal aspects of two-photon laser
Wang Yinghai, Hu Chengsheng
1992, 16(6): 365-368.
Abstract:
The Maxwell-Bloch equation of two-photon laser is analyzed by use of multiple time-scale perturbation method.We find that dynamics behavior of the system vary with various time-scale.

A study of animal model of loading fixed bridge using laser holographic interferometry
Zhao Yunfen, Wang Xiaoyan
1992, 16(6): 369-374.
Abstract:
By means of laser holographic interferometry,the animal model of abutment fixed and vertically loading bridge has been experimentally tested.The distributive law of the abutment displacement before and after prosthesis is analyses.It is sure that the animal model is a ideal test model and laser holographic interferometry is an accurate and useful test method.
