A theoretical model of laser induced thermal lens effect
Luo Taizhao, and Zheng Weihong
A theoretical model of dual beam thermal lens effect is derived. The model predicts the intensity distribution and variation in far field of the laser beam in the presence of weakly absorbing medium. Some experimental results which support the validity of this approach are presented.

2-D modulation of spatial coherence of laser light by standing A-O effect
Dong Xiaoyi, Sheng Qiuqing, Xia Shunbao, Wang Xuming, and Zhang Xiaojie
The theory on optical coherence modulation using 2-D ultrasonic standing waves is reported and corresponding analyses are made.

The theory on optical coherence modulation using 2-D ultrasonic standing waves is reported and corresponding analyses are made. Theoretical results show that when 2-D ultrasonic standing waves are used, the phase difference between two ultrasonic waves (i. e., correlation coefficient) with the same frequency and correlated phase has strong influence on modulation of coherence degree and that effect is small when ultrasonic travelling wave are nsed.Also reported are the preliminary measured results on coherence degree modulated with 2 D ultrasonic standing waves excited by two cross electrodes and AO-EO resonant coupling effects of LN EO-crystal respectively. The results agree with the theoretical analysis..

Effect of interference between polychromatic fields and near-degeneracy of levels on population of two level systems
Zhang Shenru, and Xu Yizhuang
In this paper the pumping of a two level system by nearly resonant polychromatic field is discussed. It is pointed out that owing to the interference between field, one can obtain greater population inversion in the case of pumping by a monochromatic or dichromatic field.

In this paper the pumping of a two level system by nearly resonant polychromatic field is discussed. It is pointed out that owing to the interference between field, one can obtain greater population inversion in the case of pumping by a monochromatic or dichromatic field. For the case in which the upper level splits into two nearby ones, the method of density matrix is used to calculate the steady-state solution for various parametric values. It is found that population inversion can be obtained at definite conditions..

Chen Tuqin, Ma Yangwu, and Lou Bo
A CO2 -waveguide laser tuned by a grating compound cavity was investigated. The laser operated at more than 63 emission lines and the maximum single line power is about 1W. The theory of the compound cavity was analyzed. The experimental results are consistent with the theory.

Nd:YAG laser with stable-resonator polarized energy extraction
Du Jinibo, and Li Xiuhua
A new method has been demonstrated in which the amplified beam is no longer coaxial with the oscillation beam. Thus, it extracts energy from different part of the laser rod. A laser beam with Gaussian profile and high power has been obtained. The requirement for optical uniformity of laser rod is not critical.

Cao Eryan, and Wang Kaixuan
A two-wavelength (λ1=632.8nm, λ2=488nm) Mach-Zehnder interferometer was used to determine the distribution of the electron density and temperature in argon plasma jets. The results are compared with those obtained by using single wavelength interferometry.

Variations of mode intensity spectra of a semi-intracavity He-Ne laser put into an axial magnetic field at higher total gas pressure were invest’gated. A conclusion different from the previous ones was obtained. The experimental phenomena are explained based on strong competition effect between modes.
